You can only spend ki in the amounts specified and as the action type specified in the abilities. So you can't spend more than one ki to activate one of the basic ki pool abilities, because they say you spend one ki as a swift action. You can spend one ki as a swift action for AC, 2 ki as a standard action to use wholeness of body, and 2 ki as a move action to use abundant step. If you're a monk of the four winds, you can spend 6 points as a swift action, but only to activate your slow time ability.
So no, you can't stack the swift-action bonuses.
