mystery softies!!!!!!

I've had these guys for a while. The polyp/nem was free, then i got 3 of these shrooms for $10. I was wondering if anyone can ID them.
I figure the first ones are of a long tentacled polyp, but they moved around the tank ALOT when I first got them then settled into the zoa colony which makes me think they might be a nem. It also split, this one is an inch or so from another one in the same colony. They used to live in a big clump of chaeto and would suck down into it when i let my water level drop, then follow it back up for the light.
The shrooms i think may be st. thomas's but i dunno. Color didn't come out well they are green and orange and have moved off the rock i got them on but have not split in the last couple years.
I took pictures with and without flash.

 

Pictures 1 and 2 do look like Aiptasia in the Zoanthids/ palys to me

pictures 3 and 4 do look like mushrooms, but I couldnt even guess at the type to be honest

1 and 2 does actually look like aiptasia.
3 is a shroom. What color is it? can't see the proper color from the pic
4 looks like a disc anemone/rock anemone

 

they are certaintly not aptaisa

 

I think you are correct on 3 and 4. 1 and 2 may me Majano;
