Ones a polyp of some sorts?
Ones a?
I also found a few green bubble thingys lol

Now im just starting my tank so im suprised they have survived but now that they have...should I be feeding them? And what?

No, you don't need to feed them. As long as your parameters are within reason and the lighting is sufficient, they should be fine.

Those green bubble things you mentioned might be Valonia btw. (not good)
