Sure. Thor and Hercules have clashed multiple times in different comic series. Their fights often stem from differences in power, ideology, or the circumstances of the story.
In the comics, Hercules doesn't kill Thor. Their encounters are often part of complex storylines with various twists and turns, but not resulting in such a fatal outcome.
It's hard to say for sure. Hercules is incredibly strong with his god - given strength. But Wonder Woman has her own set of powers like super strength, flight, and her Lasso of Truth. If it's a battle of pure strength, Hercules might have an edge. However, Wonder Woman's combat skills and her ability to use her tools could give her the upper hand in a fight.
