Answer if you know how to get boys to like you?

I was introduced to this guy on friday, (it wasnt planned) but after seeing him, i like him. my best friend, who has known this guy, josh, for years, was the one who introuced us. she was talking to him, and i was standing beside her, then she casually goes "this is lucy by the way, and chloe and sarah" (2 other of my friends had come along also) and josh goes "lucy" .. "so your from ____?" and then he goes to my best friend "bring your friends in here". did it matter that he only mentioned my name and not the other 2 friends? he also seemed to talk to my best friend alot more, and she reckons he likes me because usually, he doesnt talk to her much, but on this ocion he was very friendly. also, my friend told me she saw him -subtly- point to me when he was with his friend. Is he interested? he was hanging around where i was all night and being funny and stuff too. What should i do next? I only have one chance to make this work and get his number, because i wont see him again for like a month or something, please help!!
