I don't believe it's an actual Japanese name. It's simply Sora's name with the letters switched around. Sora's name however means 'sky'.
Roxas isn't an actual Japanese name. It is derived from Latin, with Roxas meaning "wind". So, "Sky" (sora) and "Wind" (roxas) share no known connection, but you can piece them together however way you want.
