people who know lots about personality types -- wanna weigh in??

Hi! I'm in the process of writing a project that deals with 5 people who are very close friends, and who live together in close quarters. I was wondering if somebody who's really knowledgeable about personality types could weigh in on how these characters might interact, clash, or go about being friends?? I know my characters very well already, but I thought it would be interesting to flesh out their relationships even further. I'll include my characters' MBTI & enneagram types, as well as their zodiac signs and temperaments. They are:

Adler ~ ISTP, 5w4, Gemini, Melancholy-Sanguine.
Dahlia ~ ESFP, 8w7, Aries, Choleric-Sanguine.
Melanie ~ ENFP, 2w3, Taurus, Sanguine.
Carmen ~ ISTJ, 8w9, Capricorn, Choleric-Melancholy.
Polly ~ ISFP, 4w5, Aquarius, Phlegmatic-Sanguine.

I'm curious as to how these types of people would function while living as a unit – who would annoy whom the most, who would be closest, how they would get on each others' nerves, how their personalities would compliment one another, etc.
Thanks so much for reading / weighing in!! <3

I just want to give my 2 cents about Carmen. I know Capricorns are usually considered to be the organized masterminds but I myself am a Capricorn and my type of organization is “I was too lazy to put it back but I know where it is.” I don’t know if that helps at all

If you're gonna do personality tests for your characters, 16personalities.com isn't that accurate and I suggest you look at other sites or look at mbti memes to decide which type fits each of your characters. 16personalities.com isn't mbti and is an entirely different typology.

I also can add that zodiac signs don't determine personality type. I'm a Gemini and act more like a Virgo, there's literally no correlation
