For your main team or generic team I would use Hinata, Kabuto, Water main, Guy. Yes you may have two healers but you do not want to. SO make your tactics of your water main rely at helping your team out with buffs. Hinata because put them out front and they will just absorbed attacks with there mystery. Guy is just very good in general with leech and can be relied on doing a good amount of damage. Kabuto because he acts as your healer also with his mystery he creates dead should which would be buffed up by your water main. If you have the summon Demon Fox I reccomend using it. But I would but that you don't so use Ninga dog shiba until Demon fox is accesible. Unfourentaly for ranked mode you do not have enough characters to make 3 solid teams. So put your generic team in for one of the spots. Then in the other 2 just fill them up with random characters that go somewhat well together until you get better characters. Hope this helps!
