As others say: Be yourself.
Also interests that you may have can also help find you friends. Whether they have the same interests or even different. You don't have to have similar interests to be friends, but I find it helpful.
Talk to your classmates, find out what they like. Open up times and ask if they'd like to go hangout somewhere sometime.
It took me quite a while to find new friends at my new school, until I found some people with the same interests as I and I began to hangout with them.
