Is it okay to not have friends?

I just transferred from a different high school and am now in tenth grade. I had been going there for quite a while a had a lot of friends, but we rarely talk now because I'm far away. So the first day of school, I thought people would notice a new kid and just come up and talk to me, but that did not happen. After a week or so I tried talking to people but they wouldn't really talk back, and make no effort to continue the conversation. Now its 2-3 months in and I don't really talk to... Is it okay to not have friends?
