Obito was soloing BM Naruto, Kamui Kakashi, Killer Bee and Gai even after his jins were released from Edo.
Obito and Madara mid difficulty at best. Naruto is still leagues below these three, add Nagato on Hashirama's side for a more fair fight. Naruto would need the other half of Kurama to be in these guys playing field and even then I assume he wouldn't be strong enough to defeat Edo Madara, Obito or Hashirama. Hashirama's Mokuton actually feeds on Kurama's chakra.
He would give them a good fight with the other half of Kurama but I just don't see him winning against any of the three listed.
