Coral Identification

Hello everyone. I went to a great aquarium store today and they had a big tank of coral frags. They had no labels on any of the frags so I was wondering if you guys could help me =). These are the pics of the ones I liked the most. They were very small most were a scant inch so I got the best pics I could.
