The first one looks like Alveopora rather than Gonipora because there are 12 pedals (hard to see from the blurry pictures but you should be able to count the pedals yourself). Fortunately Alveopora has a higher survival rate than Gonipora, but it's still a hard one to keep alive long term.
The second one is a (green) birdsnest although not sure if it's your light but it appears to be brown. That may also explain the dead skin. Give it good light and flow and it should recover. Green birdsnest is a hardy coral.
Third one is some kind of soft coral. Sorry I don't do soft coral can't identify it.
