I used pretty much the same strategy for Zao and Xu-Fu. Start with a pet that has Call Lightning, use a Firefly to apply DoT abilities, then use any flying type pet with an ability like Flock (this third pet might change when I level up Lil Bling).

For Xu-Fu, I used the Sunreaver Micro-Sentry first because Xu-Fu's opening attack is Magic type. Use Call Lightning in the first turn, then switch to your Firefly to apply Confusing Sting and Glowing Toxin, then switch to your other bird and Flock.

Just throw pets with humanoid type attacks at Yu'la and it will die eventually. You'll want to use Clock'em, Anubisath Idol, or some other pet with a block/dodge ability with a cooldown 4 rounds or lower to negate Lift-Off's damage.

3 snails makes this an easy fight. If you don't have 3 snails leveled up just go catch however many Rapana Whelks you need in Dread Wastes. All 3 snails should have Ooze Touch, Acidic Goo, and Dive.

Repeat the bracketed section until Chi-Chi dies. Chi-Chi's turn with Ethereal active should always match up with your dives.
