Any, to my knowledge. Uchiha and Hyuuga are limited though. We can reduce that to Uchiha, as people don't make enough Hyuuga to reach the limit. Rinnengan is limited too.
So unless you want one of those two you should be fine. A quick note - not all of the canon clans are registered, so if you want something like Haku's Ice user clan, you might have to make it yourself.
Hi nice to meet you! ^^ I hope you have a nice time here. I'm sort of a newbie too so if you're going to be an academy student, we can maybe train sometime. I'm Taja by the way, but you can call me by my characters name, Itami.
