Nope he would lose to all 3. You are all betting on kamui as the reason he's up there but the truth is he can't use kamui 1 vs 1 without prep because kamui is a prep tech, kakashi has to build the chakra up in his ms eye before he uses it and he would have been stomped by anyone of them before that and not to mention his kamui's warping isn't fast. I takes him a long time to warp targets that are not coming straight at him which is why he has only warped a nail fast and a susano arrow fast because they were coming directly at him.
He can't touch minato
Hiruzen would beat him before he gets off kamui or make kakashi use up his kamui on defense + kakashi has to fight hiruzen and emma and both can make kage bushins.
Sm Jiraya shit stomps kakashi neg diff simply because he is faster and the toad sage's sound genjutsu. Sm sensing would allow jiraya to sense kakashi about to use kamui so he would counter it by his extreme sm speed or launching a jutsu at kakashi thus disrupting it.
Gosh I'm a beast
