The only names off your list that are anywhere near unusual are:
Zion
Judah
Rex

I think Zion is awesome. Definately dont use Jett. I have one from pre-awesomenamebandwagon days and it drives me batty when I hear every second baby boy with the name Jett now



Some other idea's:
Chayton
Nahuel
Ari
Valentin
Elihu
Lior
Ori
Zev
Bran
Thaddeus
Caspian
Thijs
