You're right, SHIELD hasn't made spaceships or travelled to other planets. Why wouldn't Quill be able to breathe properly? So long as the atmosphere has the right gases at the right pressure and such, there'd be no problem. I mean, there is that part where actually he can't breathe properly, because he's in space without his helmet, but that's not important. And no, Xandarians aren't humans, any more than Vulcans are. Or to keep it Marvel, any more than Thor is, or any random "pink kree." They just look really like us (and apparently need a very similar atmosphere to survive).
