OKAY let's do this based on their placements haha

Jin: Jupiterian looks and jovial personality with an Aries Moon + his Mars in 5H, he is well-liked, popular, and active. Moon in 1H makes him convey expressions well so he'll be like a Troy Bolton, an athlete and a theater kid! https://twitter.com/loverofkoo/status/1355370715143413763

Yoongi: His Pisces and Cancer placements + Sun/Mercury in the 12H vs. his Aries Venus already point to him being a tsundere, seems like a cold jerk but is actually a creative soft boi. With his Virgo Moon, he's also that type who can ace things without even needing to study.

Hoseok: With his Pisces and 11H stellium, he's friends with everyone because he's the nicest guy you'll ever meet. No one could ever hate him. He's probably the one who takes the lead in organizing school festivals or any student engagement activities!

Namjoon: Virgo Sun and Libra Mercury in the 10H + Sagittarius Moon in 1H, we know that this is already a student leader combo. He's smart, good with words, and to top that, he also gets and empathizes with the plight of his fellow students!

Jimin: Also a Libra Mercury in 10H, he is a good mediator. + that Libra Sun hehe possibly teacher's favorite. If he's not with Namjoon in the student govt, he would probably be a club leader. With his Venus and Mars in 5H, he can do so many things and is a well-rounded student!

Taehyung: To freshmen, Taehyung's Capricorn stellium may be super intimidating but his classmates know that he's the opposite. His Sag Rising would make him have at least one friend from each batch. With his Aqua Venus, he's the type who always asks unique questions in class!

Jungkook: With his Libra Rising looks AND Libra Venus in 1H, his Virgo Sun, Leo Moon, and Scorpio Mars, he’s the star freshman. All clubs want him as their member as he's good at everything he does. He probably joined Jin in drama club, Yoongi in music, and Jimin/Hoseok in dance!

Note that rising/houses mentioned here are just based on rumored birth times hehe here's what each mentioned stand for:

1H - self, appearances
5H - play, hobbies, creativity
10H - reputation, public image
11H - friends, social activities
12H - solitude, hidden things
