Yeah. I don't know much about other galaxies, but there are a lot of different races where I come from. Some look almost human, but others are very different. It all depends what their home planets are like and what environment they live in.
You'd also be surprised how many places have humans. Or at least, there are a lot of us in our galaxy. I don't know how close it is to where we are now, though. I get the feeling that it's far, far away from here.
