A protagonist is a character that the story is following, while an antagonist is a character who opposes the protagonist.

The protagonist of a story can actually be a villain, while the antagonist is the good guy. For example, in Death Note, the protagonist was the guy killing tons of people, while the antagonists were the investigators and detective.

Main characters are highly significant characters in the story, who the story revolves around a lot, and that tends to include protagonists and antagonists.
