Sure! Currently, the endings in the game fall into one of three types.
1) Stat 'Deaths' (note: not all of them are literal deaths haha). These happen when any of your stats go below zero, and each stat has a unique ending associated with it! There's exactly five of these.
2) Final Challenge Outcomes. Most of the endings right now are associated with the final challenges. I think there's 10 unique final challenges in total, including debt related errands for the Witch. It looks like there's 14 of these endings! (Also, as a bonus hint, I think the only Final Challenge that doesn't have at least one unique ending is going to the gala alone)
3) Endings that Result from Normal Gameplay. I believe there's only six of these currently - three that you can get at the end of the game with the right combination of stats and traits, and three that can occur if your daughter winds up in a dangerous situation in events. These can be tougher to find, so to help you in your quest, I'll confirm that the two events that have a premature ending (right now!) are the jungle flower event and the hanging out at the lake event.
