I'm mostly trying to level Eli and Zera as tank and damage, but my only healer is Althea (is there even another one? what's Lily's ability?) and I'm not sure what the 4th slot should be.
Yeah, Eli is the best Tank atm.
Lily's ability is speeding everyone's ability's cooldown which is good for Eli and any other CC abilities. I recommend you to get Engineer Maidens, she will be useful for cleaning messy stages.
