Is this aiptasia, majano, or something else?

I'm about three weeks into my cycle and these things started popping up:
Several of these small ones - ranging from .25" to 2":

and then this big one...looks to be an inch tall and about 1 inch in diameter:

Anybody have any thoughts?

Majano. Joe's Juice will kill them.

It looks like Aiptasia sp. a pest anemone.

Looks like a majano to me as well. Either way, it's a pest anemone and both can be dealt with in the same manner - Joe's Juice, Aiptasia X (works for majano as well as aiptasia), kalkwasser, etc.

I agree that either way it's a pest. The major difference from my perspective is that a Majano can just be scraped off the rock. It you try that with the Aiptasia in your picture you will end up with a dozen more Aiptasia.
