Groups One and 3 don't like anyone from group 2. Groups 1 and 3 don't mind each other but they get in fights every once in a while. Everyone likes everyone within the groups I just place them in

No one likes anyone

First of all, you're in high school...why are you worried about it? Second of all, saying "frat" makes everyone hate you. And lastly, there are a few people in each fraternity who likes guys in other fraternities but for the most part it's a big competition and everyone wants to be the best.
