Onoki is the powerful by far. During their battle with Madara the other 5 kage were dying due to the poison pollen woodstyle jutsu Madara has used. They were literally all lying on the floor unmoving, then Onoki stood up and used Particle style to obliterate the whole forest Madara made...Madara himself stated Onoki was the one who's will he had to break.

Physically: Tsunade is the strongest due to her augmenting her chakra to boost her strength Speed wise: A is the fastest Lethality wise(whoever can kill the easiest): Onoki hands down Most powerful as dictated by Madara: Onoki.

So Onoki would kill the other Kage easily, seeing as none of them have any defence against particle style(except maybe Gaara and his sand). Gaara comes in at a 2nd place, then Tsunade at 3rd, A at 4th, and Mei is last place.
