Minato isn't a factor in any way, shape, or form.
Gai isn't a factor either considering he can't hurt Sasuke's Susanoo without killing himself, and even then it won't be enough damage to take him out, or Sasuke will just warp away with Ameno.
Obito, like everyone else here, can't react to Ameno, but Kakashi is the only one who can survive an attempted blitz due to Kamui, so he dies a swift death.
Kakashi is the main issue, as usual, but Sasuke's Susanoo should tear his apart, and then Sasuke enters close combat with Kakashi and finishes him off. It's a definite victory in Scenario 2.
-If Madara has a boost similar to Kakashi's due to his Rikudo Chakra, then he'd solo anyone on this team by himself.
-If he doesn't, then he can take out Obito with Sasuke's occasional support.
