Yang is theoretically the strongest, with Ruby coming a really close second. I can't say whose the weakest compared with Weiss and Blake, though I think it's probably Weiss.

This discussion probably isn't needed, since for all we know, Team RWBY is equal, that's why they became a team in the first place, to cover each other's weaknesses and complement each other's strengths.
