madman is when you just destroy uke with some kicks, with boomhits/boomkicks, or even single dismembers.For example: here.
Realistic is when you do real tricks, in realistic gravity, and you move like in real life. Example: here. Sparring also counts as realism. Further information about it here. and an example how it looks here.
And freerunning also counts as realism, I'm almost sure You have seen nuthug's parkour, in video or something, if you havent, then here is an example for a freerunning.
