Very cool, they're all Chalices (different companies/people come up with random names to make certain color combos seem cool/rare) except for the last which is a Favia. They all look happy =)
the last image, bottom left... that could be problematic hair algae. I forget the name, but there's a very course type that few things eat and is very hard to get rid of... might want to check on it and cut the rock. Other than that, nice job!
