Don't now about the first.
But Wayne (SM's body) would win second match, since Parker
doesn't really know martial arts, so wouldn't have much of a
chance against Wayne/SM. Wayne however, would just use
the SM super-powered body, along with his fighting skills, to
beat the completely powerless Parker.
I suspect much the same with the third SM/Wolverine battle.
Logan's fighting experience would combine with SM's body to
give him an easy win.
Diana in Supe's body would easily win. Not only would she
have the stonger body, but she is a better and more experienced
fighter than Kent (who raraely has to show skill and finess in
fighting).
Kent gets to feel up a hot body though, so maybe he's the real
winner afterall?
Magneto in GL's body wins. The ring ain't that hard to figure out. Hal Jordan loses since complete control of the electromagnetic spectrum can't be learned at a whim
Batman wins in Spider-Man's body. Easily. Class 10 strength AND 127 martial arts mastered? Petey doesn't stand a chance.
Ditto with above for Wolverine in Spider-Man's body.
WW wins easily. It's like having Batman with Superman's body. No chance. And Superman had the chance (several times over a span of a thousand years) to feel up WW but noooooo he chose the honorable route.
