Tobirama - Smarter(yeah I said it), more combat experience, also uses space/time jutsu, Edo Tensai, Edo Tensai, and o yeah Edo Tensai.
Kabuto - Stronger, smarter, more endurance, sage sensory, paralyses genjtusu, high damage AOE, Edo Tensai, coupled with his unreal chakra razor hands. Clearly an underrated foe.
Naruto - Stronger, similar speed, god-like endurance, High burst AOE and close range skill set.
Itachi (Healthy) - Smarter, Susanoo as mentioned with Madara, o yeah he's also god of genjutsu.
Nagato (Healthy) - Rinnegan, All mighty push, All mighty push, All mighty push, and o yeah all mighty push. Really WTF is Minato gonna do about this?
Sasuke - Susanoo coupled with his versatile skill set. O yeah and he's a sharingan user with Itachi's eyes so genjutsu.
Obito - Dude's a god not much needs to be said here.
PS: Encase you haven't noticed I highly doubt Minato has anything in his kit capable of taking down a fully mature Susanoo. O and Genjutsu should also work on him based on his kit.
