Do different wings have different A of A's?
Yes, most certainly. Low drag swept wing designs can tolerate incredibly high AoA as can delta wings, just look at past footage (sadly) of Concorde on Final approach. They are generally low lift wings with about +3deg positive pitch in the cruise at umpteen-loads knots, as the speed decays they rely on high AoA (as well as high lift stuff like slats'n'flaps) to stay in the air.
As for chord/span. Flaps increase the AoA of the wing, creating more lift, hence the reason why you can pitch at cruise attitudes when well below cruise speed.
