Ock is a normal human with robotic arms,so idk how in the world he was able to tank spideys punches.So flash should be able to take him out atleast,given enough time.
HMm proly not SvsFL,considering he was able to stop that train + held that huge piece of metal at the end of spiderman 2.Id say his feats are pretty consistent.
The rest win,flash will get tired eventually,which means the moment they get their hands on him he's dead.
