Hello

I really don't see anything in the last two pictures. The first picture I see what looks to be some GSP growing. (Green star polyp). My husband and I both have huge colonies of it. Some people don't like it because it's a fast grower and can take over a tank quickly but if you keep it in check there is nothing to worry about. I would however remove it from the frag of palys. It needs to be in its own area. GSP is easily removed, it's almost like a carpet and you just peel it off. Hope this helps.
