Sarge is a good height for a realistic human male. Could be taller, but still a decent height. Jak was a freaking basketball player or something.
Nyx is, of course, fairly tall for a human female.... okay, she's really tall (sort of. I mean, Ven was 6'6" or something before she was reborn). Of course, she isn't exactly a homo-sapien.
As for him being the shortest... I think he actually comes close as long as you're limiting it to the adult human males.
