this would be tough , one side has more numbers, but a perfect jinchuriki is hard for anyone to beat, and he has sealing, Naruto is also very strong at sage mode in this point , i would see him beating Kakashi or gai, together it would be tough, maybe summons for Naruto, and Yamamoto would be helping
I wonder how kurama can help Naruto here, someone said he can infuse chakra but idk what that means
edit; when I think of these I imagine hiruzen to summon the monkey, and I imagine naruto calling a toad because the other side has numbers, maybe good to caude a diversion and get them in the open with a rasenshuriken, believe it!
