Well I'd go for Naruto and J-man:Infinite Chakra for both will be great for a battle like this one, They have multiple summoning, Naruto was able to make like 15 shadow clones, kage level, don't even vanish after 1-hit.
We saw already what Naruto did to those Edo Zombies
J'man has sealing aptitudes
Naruto and Sasuke are suppose to be around equal and J-man is above Kakashi Imo
Tsunade and Sakura are good healers but they'd simply be overwhelmed
Raikage would loose to Naruto, and J-mans oil would pose a problem to Gaara's sand
Kisame wouldn't be able to absorb all the chakra of KM and Itachi would be overtaken 2-1
J-man can deal with Lee in Sm and Naruto with Guy in KM
They don't exactly have infinite chakra. For Jiraiya his chakra must blend with the natural energy but when he runs out of his own chakra he must stop using techniques because if continues to use natural energy he'd turn into a toad.
Beyond that you're assuming Naruto can take on all those Edos at once. And Jiraiya would just come behind and seal them but they are going to be in a battle royale so odds are things won't happen so easily. If you can imagine the 3rd Raikage, Madara, The former Jinchuuriki, Muu, and The 4th Kazekage, Hashirama, and Tobirama all attacking at once. Furthermore Madara and Hashirama would be able to suppress the Bijuu chakra. Especially considering not only does Madara have mokuton but he also has rinnegan and preta path.
Tsunade and Sakura aren't just healers. They are both pretty good at evasion. Tsunade has been blitzed twice. Sakura was overwhelmed by the arm sand but just created a strategy to get past it. When they can't over power their enemies they can think of other strategies. Tsunade attacked Madara with the Susanoo sword to open up an attack for the other Kages. When the only defect Oro had was his arms (meaning his body was perfectly healthy) She ended the fight with a single punch. This being the same man who was extremely sick went toe to toe and took several hits from 4-tailed Naruto. Katsuya as a summon would be incredibly helpful. You have healing. She can be used as a shield as she splits as she pleases. She can be thrown as we know even her mini versions are heavy. Jiraiya implies that Tsunade can seal and we know from the fact that she created the seal on her forehead and can even divide it into stages that she's talented with seals.
Sasuke currently isn't near Naruto. Maybe soon but with the KM boost he's just behind. Everyone here is pretty much stronger than Kakashi with perhaps the exception of Sakura. Raikage has one technique which doesn't exactly make him difficult to predict. Bunta's oil, Katsuya's acid, and Tsunade's strength would pose a problem to Gaara's sand. We don't know if Kisame can absorb of Naruto's chakra. He may be able to. But Naruto would have to overwhelm him with taijutsu. The natural chakra wouldn't be going into kisame if he used his Water Release: Great Shark Bullet Technique rather it weould just power the shark. Jiraiya vs Itachi is debatable
So I stick with my original statement. Oro and Kabuto would win unless they needed to summon their edos which would take time and they would be the focal point of all offensive power to make sure the edos don't screw everyone. At which point either Tsunade and Sakura, Jiraiya and Nartuo or Itachi and Kisame walk away with this.
