Can I fix this with braces or do I need surgery? (Photo)

I have no idea how bad my teeth are, I know they are in a bad position but don't know the severity of it, can someone please explain to me what I need to do? How severe is it? I had a deformed tooth and my orthodontist decided to put a crown on it until the tooth above it could fully erupt, can the tooth that is up above be saved, or do I need to extract it? Thanks in advance!
