I agree with SP first 2 pics is over an enchinata acan keep away from most anything you dont want killed as they have a very strong sting and can be highly aggressive toward other corals
the first pally polyp looks like a common pink coco pally to me
the second couldn't tell ya a name for it but it is a pally I think hard to tell size in the pics
The first pic looks like a dendro or a sun coral, i have no idea on the second pic, the 3rd looks like washed out kedds & the 4th looks like washed out candy apples
