hashirama, i doubt, his mokuton gave him the edge and now madara has it. So even if he will win, it will be mad tough.
Sasuke - no no no!! Madara is wey better than him. I don't see how he is going to win with amaterasu or susano'o. madara has the same shit, haven't seen him use amaterasu yet though.
Tobi - with his gedo mazo and 6 jinchuriki paths i can see him snatching this. Good with the eyes; both sharingan and rinnegan and can enter susano'o as and when he likes.
Naruto - even if he could it will be tough, with rinnegan madara can use preta path abilities and drain all his chakra. But there is sage mode, and he was able to combine both (when he went to see nagato) so if he does that i think he'll give madara a run for his money.
Nagato - it'll be tough, it'll be long, both have very good chances of winning. But nagato has better mastery of the rinnegan than madara and greater chakra reserve. But mokuton with the rinnegan i think madara barely takes this one.
Minato - ftg + rasengan combo and its over, all he needs to do is place a seal or throw a kunai. If he is able to, game over for madara but if he can't i don't see him winning.
Itachi - with his sword of totsuka he could get lucky. He can block any attack with his yatta mirror. He has a chance, not that big but he's smart, he'll know what to do.
