the first one looks like a pineapple sponge. the second one I don't know, some type of calcerous algae, maybe?

Sponges. No need to worry. The fist ones, though the pics aren't celear, look like pineapple sponges. The last one I have in my tank. Don't know the name though.

Yeah, pretty sure. If it's not a sponge it's still harmless. I have a bunch in my tank and they've grow to look pretty cool.
