Very tough. Prior to Kuma's full transformation he would certainly be on the top - just because the nikyu no mi is so overpowered. The ability to repel everything is the ability to repel everything, no further discussion needed. However, now that his brain doesn't function he is just another mindless Pacifista with the extra power to create air blasts. Guess in a battle royal he would be taken out easily by the other Shichibukai.

For Jinbe, it heavily depends on the environment. Unbeatable underwater, on land still strong enough to beat at least Moriah and Hancock (I doubt Jinbe has impure thoughts, making her df next to useless). He probably would hold his own against crocodile by manipulating water, but encounter problems with Mihawk (if it is a land battle).

Crocodile... again tough. His devil fruit is insanely strong, but his weakness is so easy to abuse. He would probably fail against Jinbe and Mihawk, but manage to hold his own against Doflamingo, Kuma, Moriah and Hancock. If you doubt his power, refresh your memory of his abilities by watching the Arabasta arc again.

Moriah, a very sad fellow. His devil fruit is amazing, but unfortunately not for one-on-one fights (compared to other Shichibukai). He would be the punching ball of the battle - maybe with the chance to injure the braindead kuma.

For Hancock....it is a similar situation. Her abilities are amazing against a huge army, but I doubt her hand-to-hand combat is enough to keep up with the other warlords.

Mihawk. Not much is known about his true powers because he doesn't care most of the time. But: You are not feared and respected by simply being the strongest swordsman. In a world where the powerful figures are nearly invincible, especially to cuts, one has to develop ways to keep up. Nothing is confirmed, but I'm damn sure he has a high mastery of Haki. That said, I believe he could win against Moriah, Kuma, Hancock & Crocodile.

Doflamingo. Like others mentioned, impossible to guess. His power doesn't work against Crocodile, which implies that he can not control intangible matter.

So my scenario would be: Kuma < Moriah < Hancock < Crocodile < Jinbe = < Mihawk = < Doflamingo
