Help me identify these stars and urchins

Here is the fist starfish I think maybe it's a red sea star like on this link:

The other 3 little guys I'm not sure about. My LFS said they will eat what they come across and I feed a blendermush to the entire tank. Do I need to actually target feed each of these?

i know there is a certain knob star fish that eats reefs, hope yours isnt one of them

I'm sure with my luck mine will, probably have to get rid of it when I get corals down the road. I tried finding out what they were before I bought them a little while ago but couldn't find anything so I figured I'd at least keep them until I start buying corals etc.

There are harmful urchins as well. I dunno if that's one of em' but WOW how beautiful.

Without seeing the top of the first star, it looks much like a Fromia sp. as well. Quite reef safe.

The urchin looks like a pincushion species... Primarily an algae grazer but this type will strip coralline quite quickly. I would also not trust it in a coral reef tank.

The last pic very much resembles a Fromia milliporella as you've already found.
