Madara can solo them neg diff, the only problem is 4th, he will escape.
Minato would end up the same way as Tobirama, his reaction times are slower than the latter.
Madara hasn't shown the ability to seal Edos, so no.
Besides, they are needed.
He does know seal techs, there's probably a op rinnegan jutsu.
That's just a presumption, no feats = no dice.
SO6P = No feats = No dice U_U
He created the moon moments from death, pretty big feat if you ask me.
We've not seen it have we? For all we know it was a baseball-sized and the people telling the stories lied U_U
Madara used the Gedo Mazo sealing chains. He also wants to become Juubi's Jinchuuriki, and that implies he has Fuinjutsu.
They're chakra chains "Mazou no Kusari" not sealing chains, besides that's just Madara manipulating/controlling the Gedou's technique.
