Out of the ones you listed...Tetra sounds the best to me. But I'm also going to echo people and say not to pick something too exotic or you will regret it. Maybe not right now or in a year, but the older you get and the more you want to settle into 'normal life' the more a hindrance that cool and weird name will be.
And quite honestly, a couple of those names I would liken more to stripper stage names or drag queens.
