avoiding friendship with teammate without being mean?

corps/group name: ACE EPIC individual placement

I’m on a small team of people, previously four, now three. There’s one guy on the team who I don’t like very much. He’s not a bad dude, we just have conflicting personalities. I don’t like the way he talks, his sense of humor, etc., but he is very friendly and talkative and is the type to want to make friends everywhere he goes. i sometimes like talking to him but I’m afraid if we get too close he’ll want to be actual close friends. I don’t want that and stating it directly seems mean. he’s not great at picking up subtle social cues, but he’s also not very blunt person, very nice and midwestern. 

I like my other teammate, but I don’t want to get too close to her either, because it would be awkward to get close to one person and not the other. 

I guess all I can do is keep being nice but relatively distant. so i guess i basically know how to handle it, but does anyone have tips for keeping yourself entertained when you’re not close to your teammates? how have you guys dealt with not liking people on your crew? how do you live and work amicably with someone who likes you a lot more than you like them?
