!NEED DATING ADVICE!?

so there are a few guys that i like but idk if they like me and i don't know if they just want to be friends or if they kinda like me too. the first guy, trevor, he is a twin at my new tec school. we talk all the time and i want his phone number really bad but i don't know how to ask for it.....the next one, jon, is in my lab class and i know he is single but he always talks about other girls that he likes back at his home school. i have his number and we get along great. how do i say i like him....the last guy would be out there but hey. so i have known this one since like 2nd grade and him and my brother and me did everything together. over years i quit hanging out with him cause of the whole boy girl thing and i started liking him about 3 years ago. he comes over sometimes to spend the night with my brother but that's just it. hes my brothers friend. hes a freshman and im a junior. and he has a gf but i think he might kinda like me and idk what to do on that one either....so if some one could help me on things that would be great.....:)!NEED DATING ADVICE!?
