Codi Zrgaat & Fabula Cavataio: Codi would probably hit on Fabs immediately. Fabs would blush and wave her off, and Codi would move on to more enticing prey.
Codi Zrgaat & Elizabeth Sunrider: They'd probably be on opposite ends of the same fight. Liz would get her butt kicked for a few minutes, then surrender.
Codi Zrgaat & Razelle Breuner: Uninhibited, physics-breaking sex. For hours. For days, maybe. Both of them have n+1 libido and are extremely tough.
Elizabeth Sunrider & Fabula Cavataio: Lawl curbstomp.
Elizabeth Sunrider & Razelle Breuner: Lawl curbstomp.
Now, for the interesting one...
Fabula Cavataio & Razelle Breuner: Chance has it that these two are required to fight in this instance, and what a helluva fight it'll be. A little like Batman vs Superman, Razelle's chances at victory improve dependent on how much time she has to prepare. If thrown into a situation without her gear or any planning, Fabs would probably beat her into unconsciousness in the space of fifteen, maybe twenty minutes. If she had her standard field gear but was otherwise taken off her guard, it would probably wind up being a tie; Raz is trained in anti-FU tactics, and Fabula can outheal blaster damage/martial arts injuries/knife wounds.
But if you give Raz about twenty minutes and some resources, Fabula would be the one down in a few minutes. Razelle is brilliant and has years (centuries?) of experience and specialized training in taking down Force users. She fights dirty, ambushes, goes for overkill, and thinks on the fly to use her surroundings to her advantage. Fabula could withstand a couple of shots, a few hits, but when she gets buried in a landslide, riddled with blaster bolts, hit with a series of K'tara nerve strikes, and blown up with a grenade? Batman Razelle wins.
