This would most likely be a stalemate. Hulk up against Superman would result as even. Superman was killed by a Hulk-level enemy ONCE. Doomsday. Doomsday, after that event, was beaten by Superman every other time. But if you said Thor and Superman, Thor has magic and Superman is vulnerable to magic.

Batman and Captain America are practically even according to training but combat tactics from Cap would prob give him top but Batman predicts ahead any moves he has. Even once again. Oh, and Batman has beaten all of the core JLA before.

The Flash has turned back time once (Flashpoint) and can probably do it again. Martian Manhunter's a psychic and could possibly easily defeat those who aren't shielded from his powers and he's intangible too. Green Lantern is pretty powerful and yellow doesn't affect him anymore. Wonder Woman is practically a demigod and could take care of some of the Avengers. She's second to Superman.

Black Widow has martial arts skills but wouldn't stand a chance against the likes of The Flash or Wonder Woman. Iron Man is pretty tough but Green Lantern has a tougher arsenal by just using his imagination! Ant-Man and Wasp could be taken care of by Green Arrow and the Black Panther can easily take on Green Arrow and Aquaman.

Verdict: Stalemate. Most of the heroes you mentioned are almost evenly matched in power.
