Looks like a pineapple sponge, to me. They are filter feeders and are beneficial.

It does look like that. But I also read something about vermited snails?

They have hard shells and an opening

Vermitides(aka tube worms) do not have a sponge like appearance. They look like little tubes sticking out of rocks that project a mucus to trap food.

I have little web looking strings that come out of the rocks, and they move to different spots.

Could this be something from them or is it a sponge?

I've also noticed a very very small dime sized brittle star.

This is a great website to help ID all the little things crawling out from your rocks.

Yes after looking there it seems to be a sponge.
