Onoki is the most 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.. Onoki was also the one that saved A from being killed by Susanoo(as stated by Madara himself) and also was the one who used particle style to destroy all of Madara's susanoo clones. 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.

To be honest, this shows just how weak the 5 kage really are. Onoki and Gaara are the only exceptional ones. Tsunade's is slow and strong, and for those users reading, she never hit Madara, the body she hit was Madara's wood clone(also stated by Madara himself). There are several ninja 10x more powerful than the any of the 5 kage during the war arc feat wise(excluding Onoki/Gaara) like; Itachi, Sasuke, Obito, Killer Bee, Kabuto, and Pain/Nagato.
