I would say that “fraud, defraud” are more common in non-fiction or business language. “Bamboozle” and “swindle” are quite literary, but can occasionally be found in regular slang, although using the former in a cocktail party or a bar might get you some weird looks. “Scam, rip-off, and con” are very informal, but almost everyone will know what you mean. They are all largely synonymous, but it really depends on context and degree. A politician or public figure who uses deception, rhetorical prevarication for personal gain may be described as a fraud, but not a swindler or a con-artist. The latter two refer more to street peddlers or salesmen who try to trick you into buying their ware. Someone who frauds? Perhaps a con-artist, deceiver, liar...depends on what type of trickery was used.

They are all similar and somewhat interchangeable, but have slightly different connotations.
