The coral in the first picture are Hairy Mushrooms. The second one is a Goniopora.

As far as the clamped fin goes this is usually an indication of an illness of some sort.

Agree. The second is Goniopora, perhaps Goniopora burgosi. For corals check up here https://www.livestockusa.org I saw similar when diving in the Andaman Sea, Thailand https://tranio.com/thailand/
