In the stance that someone is gay (boy/boy) or (girl/girl)
1. Is it haram for them to have physical contact with someone they are attracted to? Like if a guy hugs a guy he’s attracted to (in a friend way) but the one that’s attracted thinks more than that. Does it make it haram on the guy that’s attracted
2. Is it haram for them to do things friends would do even though in this case both in this case are attracted to each other such as become roommates, have dinner, spend the day together… etc

Yes it’s absolutely forbidden. Visit Sayyed Sistani website on matters of homosexuality.
