I have 6 closers on my roster. I have Corpas in case of a Fuentes trade. Do I need to try and trade some closers? Maybe package 2 closers for another positional player? Who are my must keep closers? This is team 3 in sig.

Where do you currently rank in saves? I'd say yes you have too many but in a 10 team league it would probably be hard to trade the fringe guys like Corpas, Fuentes, and Kobayashi

Since it's H2H I'd definitely say you have too many. I'd try to package any one of them and another player for an upgrade. I'm not a big closer guy so I'd trade any of them.
