Re: How to be friends with a person in my class?
How is that if he is in your class? 
Anyway ask around, I am sure other guys or girls know his name. Don’t be all shy, be confident and ask one of your mates “WOT’S HIS NAME?”. Who cares if he knows you are asking around for his name? The worst that can happen is he will come to you asking you why and that is actually good, so then you can tell him, oh because I wanted to add you on Facebook but was too shy to ask you directly and he might appreciate that 
Just get out of this freaking shell and definitely try the Eye Contact, the pen thing and the getting in to a group project thing.
Oh and if he participates in any club or extra curricular activity, join it! If not in class, I am sure you might get an opportunity to talk to him over there!
