First of all, he is using dust release as his regular jutsu, not his ultimate.
Also, he seems to be floating in the air just like onoki.
Now the 3rd raikage
Not much to say except that it looks like ration armor is activated and he is using hellstab as his main jutsu
For the 4th kazekage
Similar to gaara, but uses gold dust instead of sand
Looks like joki boy is his regular jutsu
