In this guide I will list all of the girls available in HunieCam Studio, their starting Talent and Style level, their Fetish specializations, and their level of boozehoundery and/or walking exhause pipe. They are listed below in order of Stress gain from highest to lowest. I also put them in convenient little groups with totally inoffensive and appropriate titles that best describe them. I also briefly summarized their character in a totally unbiased, strictly objective point of view.

Though they are the first starters in history that can't evolve, you have to pick at least one to begin the game. They all share exactly the same Talent and Style level (1), and none of the three share a fetish with each other, while simultaneously sharing one fetish with at least two other girls each. As there is no way of knowing in advance how many Promo opportunities you will receive for each fetish, you literally cannot pick wrong here.

TL;DR, pick your favorite.

Former Barista-turned-Streamer-turned-Camgirl, Nikki has inexplicably discarded her general distaste for sexuality to engage in sexuality for everyone to see. Since HuniePop, Nikki has: grown two years older, two cup sizes larger, and gained 28 pounds.

• Huge Tits - I'll say. As stated above, she has gone up 2 cup sizes in 2 years.
  
• Glasses - Water Type.

One year before(?) rebelling against her decadent pornstar mother, Tiffany apparently financed her college career by becoming a part-time pornstar. Best known for her girl-next-door personality, Tiffany is (clearly) not shy about sexuality.

• Teen - She is now a year younger than she was in HuniePop somehow.
  
• Fit - Tiffany ate three pounds of Shakin' Bacon for HunieCam, but she is still in great shape!

Three years after HuniePop(...wait a minute...when the ♥♥♥♥ does HunieCam take place? Oh whatever), Kyanna finally quit her job as Audrey's personal, full-time stylist and took up spreading her legs on camera to pay for her toddler. While it may seem like tempting fate to assign her unprotected sex in a Sleazy Motel, fear not; pregnancy is not an STD so it can't happen while there.

• Latina - To fill their list of fetishes without going into real fetishes like, say, fisting yourself in a playground wearing nothing but fur boots and a gas mask, races other than White are a fetish. Plus, we have a three-MILF-limit here at the studio.
  
• Thick Ass - Giving birth may or may not have had something to do with this.

Presumably as a result of their tendency to get totally (and mysteriously) wasted before dates, Nikki, Tiffany, and Charmander never smoke, nor drink. Thanks to this, they will never consume your stockpile of smokes and booze. This doesn't make them automatically superior however, as all three become stressed much faster than any other girl.

After those cringe-worthy Pokemon references, I'm sure you're eager to learn about the rest of the girls you can recruit. Let's get this out of the way now: from this point on, you have to deal with at least one vice when you employ the remaining fifteen girls. These three are the least drug-addled of the lot, but still require occasional upkeep from the Liquor Store and Corner Store. In exchange, they get slightly less stressed out than the Starter Trio. They also don't evolve.

Trading annoying passengers for annoying commenters, Lola is three years older (so, I guess from the same time period as Kyanna) and has either become way less outgoing or way the ♥♥♥♥ more, depending on who you ask.
Talent: 3 - She has clearly learned a lot since her debut.
Style: 3 - Lola is no stranger to style.

• Ebony - But we can't slap Ivory on the white girls and call that a fetish. That would be racist.
  
• Fit - Apparently "Fit" means she gained three pounds (like Tiffany, if you ignore the whole time paradox thing) and simultaneously lost a cup size. Don't ask me how this happened. I don't biology.
  
• Sometimes Drinks - Have some wine with your in-flight meal baggy of peanuts.

X years before HuniePop 2: Audrey Strikes Back, Lailani entered the temporal nexus that is HunieCam. I think. Lacking the character development of the HuniePop girls, all we know about Lailani and the other newcomers comes from their short bios and wild mass guessing.
Talent: 3 - She apparently knows what she is doing.
Style: 1 - I would beg to differ, but ok.

• Asian - Chinese-color. In all seriousness, her name and bio implicate Hawaiian descent.
  
• Flat Chest - One of the legendary three who possess the rare DFC. If we stick with the rapidly aging Pokemon analogy, this makes her Articuno. Because islands.
  
• Sometimes Smokes - Just like the volcanos back home!

Hailing from the future, Beli is five years older and eight pounds heavier. She is not at risk of diabetes, but people exposed to her most definitely are. Beli has also gotten in touch with her inner pervert, as we all suspected was the case.
Talent: 2 - Comes with being a closet freak.
Style: 1 - A little too much Sari

• Asian - Because Indian would complicate the game.
  
• Chubby - Oh please, she is Hollywood Chubby at best.
  
• Sometimes Drinks - Why am I not surprised?

These group names might be getting progressively more racist, but I lack the creativity to come up with something better for these three. While they don't all share a skin color, they do share a level of reduced stress that only comes with increased drug abuse. Don't let any so-called therapist or doctor tell you otherwise; drugs are the best way to reduce stress.

Our second new girl to the franchise, Renee is working her way up the actress totem pole by working her way around the stripper pole, well aware that the best way for women to advance in the industry is via sex.
Talent: 4 - What I'm saying is, she is working the pole.
Style: 4 - As expected of an aspiring actress.

• Ebony - The top of the cookie.
  
• Thick Ass - It's hard to tell given the art style, so I'll take their word on this.
  
• Frequently Drinks - Training for Hollywood parties.

Only slightly less bland than Renee, Candace represents the gold standard in the American porn industry: white, dumb, and fake. That said, she is a professional stripper, so she probably knows more about the industry than any of the previous girls.
Talent: 5 - Being a professional, this is to be expected.
Style: 3 - Her style is cosplay.

• Ivory - The creamy center.
  
• Fit - Unfortunately we cannot confirm whether she has gained three pounds since HuniePop.
  
• Huge Tits - They're apparently an F cup. I am being told the "F" here stands for "Full of Silicon".
  
• Frequently Drinks - The gold standard.

Aaaaand now we go from bland and flat characters to full-on try-way-too-hard. If you are more unique than Zoey, consult your psychiatric care doctor. Apparently identifies as an android, but she has yet to demonstrate superhuman feats or a sufficient power level.
Talent: 1 - Androids are not famed for their sexual prowess.
Style: 2 - I...guess?

• Ebony - the bottom of the cookie.
  
• Flat Chest - The second of the legendary three, I guess we can call her Zap- ok I'll stop.
  
• Frequently Smokes - There's a shocker.

These five serve as the average of the lot. They get stressed less, consume booze and smokes more, yadda yadda, you get the idea by now right? They also have enough makeup between the five of them to make a large painting, and are incidentally all new characters. Now I'm not saying there is a correlation here. I'm saying there are three.

Rumor has it that Marlena moonlights as a Camgirl when she is not being a psychiatrist on a long-running soap opera. My sources are non-existent and my claims are completely baseless, but that's the story I'm going with because there sure as hell isn't a better one in the game.
Talent: 5 - I feel like there is a story behind these stats, but the details are unknown.
Style: 5 - Supermodel-tier.

• Latina - Brazil flavored.
  
• Huge Tits - Her and every other porn star in existence.
  
• Sometimes Drinks and Frequently Smokes - If you don't have anything nice to say, don't say anything at all.

Not-Audrey, i mean, Yerdua, sorry, Lillian "hangs out at the mall and does pretty much anything her parents-" ok you know what? As far as I am concerned, she is secretly a Magical Girl.
Talent: 2 - I assume this also includes magical talent.
Style: 4 - clearly referring to her unseen magical girl transformation.

• Teen - Appropriate magical girl age.
  
• Tattoos - They're like scars, but self-inflicted!
  
• Smoking Addict - Speaks for itself.

The Goddess of Sex in the Russian pantheon, Nadia joins the ranks of MILF. The fairies in my head tell me she used to be (or maybe still is) in the KGB.
Talent: 2 - Not a lot of talent for a Goddess of Sex and former escort.
Style: 2 - Not a lot of this either. See? KGB.

• MILF - I'd make a demeaning joke here, but I don't want to make my bias that blatantly obvious.
  
• Tattoos - see above
  
• Sometimes Drinks and Frequently Smokes - There's probably a stereotype here, but I'm not seeing it.

Nothing I say can possibly make Sarah look worse than she already is, but I will try. Serving a life-sentence exposing herself on camera for adopting the Ganguro style and exposing it to the general population (an action that is under consideration for classification as a war crime), Sarah is in possession of 50% of the makeup in her group.
Talent: 1 - Yeah I can see that.
Style: 3 - ........nope.

• Chubby - Really?
  
• Thick Ass - These are the fetishes we're going with? Not the wierd-ass fashion genre from Japan?
  
• Sometimes Drinks and Frequently Smokes - Is it too much to ask for a new character that does neither?

If Jessie wasn't a professional, she would be Brooke. Still, she is a refreshing character after the travesty that precedes her, so there's that. Her bio doesn't explain what her profession is, but "business woman" can easily be taken as Alligator Wrangler, so I'm going with that.
Talent: 3 - Apparently why her husband can't keep up.
Style: 5 - The latest in Alligator Wrangler brand-name products.

• MILF - If that's you're thing.
  
• Glasses - Stylish and sexy. They also help for spotting Alligators.
  
• Frequently Drinks and Sometimes Smokes - The opposite of three of her friends.

Now we're really digging into the drugs stockpile. If you don't have the accessories to mitigate their vices, Aiko and Nora will be pretty draining on your resources. That said, they're both pretty chill and don't take ♥♥♥♥ from anybody.

Japanese, loves birds, and a classic student fantasy. A year after HuniePop, Aiko has gained three pounds (but is not "Fit" I guess) is rockin' B's (did she have a reduction!?) and was fired from her job as a university professor for sexual misconduct with her students. I wonder how that happened? I'm sure there's a story there.
Talent: 4 - Oh my, yes.
Style: 2 - Is the sexy teacher look not "in" nowadays?

• Asian - As was made explicitly clear in HuniePop, Aiko is still very Japanese.
  
• Glasses - You just can't go wrong with glasses.
  
• Addicted to Drinking and Sometimes Smokes - As expected from a gambler.

In the running for memetic badass of the HunieCam cast, Nora is rumored to own a gatling gun that shoots fists. Probably tied in some way to a cartel, it might be best to maintain the camera distance.
Talent: 2 - Somewhat surprising.
Style: 5 - Cartel-bought clothes.

• Latina - Retired drug dealer? Check. Latina? Check. Totes cartel.
  
• Tattoos - Cartel!
  
• Frequently Smokes and Drinks - Required for badasses.

Hoooo boy. Be warned, if you do not have the accessories that stop consumption, you will be sending girls to the store a ♥♥♥♥ ton. And you had better send these two, because they acrue the least stress of all the girls and can therefor handle tons of activities before needing to be sent to the Spa.

Tiffany's mother is the same age as she was in HuniePop, so they're probably from different time streams. The Christmas MILF returns for more unadulterated adult acting as the poster girl for HunieCam Studio.
Talent: 5 - HuniePop players are already quite familiar with her talent.
Style: 2 - Needs work.

• MILF - the codifier.
  
• Chubby - I don't think I have the same definition of Chubby.
  
• Addicted to Smoking and Drinking - Much to Tiffany's chagrin.

Last but definitely not least, Best Girl returns to spread the word of Mega ♥♥♥♥♥ through the internet whilst also spreading her legs for the internet. This iteration of Audrey must have hit a few bumps on her way in the time machine, because she is three years younger, two pounds heavier, one cup size smaller, and recently broken up with what was implied to be the protagonist of HuniePop...in which she was 21...before which she was a virgin...so either she never had sex with the "boyfriend" or she's making him up to excuse her drug habit. Audrey being who she is, I'm willing to bet on the latter.
Talent: 2 - All that BJ practice pays off!
Style: 2 - WHAT?! ♥♥♥♥♥♥♥♥♥!

• Mega ♥♥♥♥♥
  
• Teen - The biggest time paradox!
  
• Flat Chest - Flatter than before, Audrey is the final legendary DFC and strongest of them all. She is fire type.
  
• Addicted to Smoking and Drinking - Arguably worse than Jessie, but sadly doesn't gain any extra benefit.
