It's hard to say. This would be an extreme case of what is known as Convergent evolution ( http://en.wikipedia.org/wiki/Convergent_evolution ).

Because the life featured in the Star Wars franchise did not evolve from the same common ancestor that humans share, they ar not part of the human clade. In fact, they are not even part of the animal clade. So not only would they not be considered humans, they are not even animals.

But, there is still the hypothetical possibility that on the genetic level, they are close enough to humans so that they could not be distinguished by their DNA. If this is the case, then humans could mate with the humanoids like Luke Skywalker, Leia and so on who are referred to as humans in the films, which would prove them to be the same species as humans.

It is an impossible distinction to make because this level of convergent evolution has never been seen in the real world and is likely impossible without some sort of deliberate human interference.

It is safe to assume that the "humans" from Star Wars could not reproduce with the humans from Earth because they share no common ancestor. This would make them not humans, not mammals, and not even animals, but members of a completely separate Kingdom of life altogether.
