Lmao my bad man. I couldn't resist.
But seriously, they probably beat all of them except Minato. Mei/Kisame is a brutal stomp, and Orochimaru vs. Byakugo duo is a one sided matchup. Tsunade or Sakura alone could deal with the majority of his arsenal, put them together and things like Hydra aren't even a major factor. They rape it with their strength and with 10% Katsuyu's acid. As for Mei and Kisame, Kisame isn't even a threat against them without Water Dome and Samehada. They'd engage him and one shot him with a punch, and Sakura or Tsunade would easily defeat Mei.
-Shockwave of the punch can displace Acid Mist.
-Byakugo lets them fight inside of it.
-Once they close the distance, and they will, it's a rape as Mei stands no chance against either of them in close quarters, especially Tsunade since she's actually a Taijutsu Master (5 in DB)
Gai and Lee don't have the firepower to put them down, nor can they outlast them. Kakashi and Gai have a much better chance, but if they rely on Katsuyu and their AoE they should be able to take home the W considering Kakashi won't survive their punches even if he's just caught in the blast range.
Pain Arc Naruto...in pure CQC Tsunade and Sakura would take him. FRS is the only jutsu he has at this point that I see disabling them in one shot. Naruto only has 5 minutes in Sage Mode too. If they can evade FRS both times they would win, that or survive for 5 minutes.
If he's able to call on Ma and Pa he'd win though, but if he never gets to summon them I don't see him winning.
