They shouldn't all walk together unless you make them all start the walking animation at the exact same time.
Also, I wouldn't use animate myself. I would use animtime and set the frame manually, because that allows you to slow down or speed up the animation depending on the walk speed, which also adds more variation to the movements of the characters. YOu'd also want to vary how fast each character runs.
