Crashed Tank Coral ID Help

[GFX360x]

I picked up a few corals over the weekend from a "crashed tank". Any help ID'ing these would be greatly appreciated.

I've stuck mostly with soft corals and LPS but decided to try out some sticks and see what happens.

I dipped these in coral rx and put them in the tank yesterday evening

Thanks in advance!

1. I believe this is a birds nest, but not sure of what type.

2. I have no idea what this one is

3. Looks like green velvet

4. Pink polyps, pretty sure color is way off (bleached or stressed)

you’re correct on the first one…
it’s a ponape/birds of paradise birds nest
i think the second one is a acropora valida
fourth is maybe a branching monti (could be wrong)
