so where do waluigi and wario fit into this? are they both younger thean mario and luigi?

That's a good question that.

Wario was a childhood acquaintance of Mario.  Basically all of Wario's antics are him trying to get revenge on Mario for Mario being mean to him while they were growing up... or something like that.
