The 3rd is definitely an Aura thing.

The first one, I also wana say you're probably capable of doing it with Aura as well (I'm thinking that one shockwave move Sun used in Black and White, and Blake's slash wave against Roman in No Brakes are both Aura based).

And the second idea, I'm thinking it could work as a Semblance as long as the people looking at the user don't get permanently blinded.
