Calo's strong, but he's stupid. Canderous is a great warrior, but he's aging fast. Mira's got the Force, but she's always been second to Hanharr, who when in a rage is super strong but more easily tricked.
Zalbaar would go first, just because he's Zalbaar. Next would be Calo because he'd try to take down the thing who's pelt would earn a little cash and end up getting shot by either Mira or Canderous. Mira would go next, because she's really just a padawan, and Canderous has fought much more powerful Jedi than her. In the end it would be Canderous and the rabid wonder, but I still think Canderous would trick him into stepping on a mine or something. A man with strength as well as intelligence is a very dangerous person.
Then HK would shoot him in the back and declare himself the winner. "
