Dawn of Hope — ruling 1

Each creature with lifelink dealing combat damage causes a separate life-gaining event. For example, if two creatures you control with lifelink deal combat damage at the same time, Dawn of Hope's ability will trigger twice. However, if a single creature you control with lifelink deals combat damage to multiple creatures, players, planeswalkers, and/or battles at the same time (perhaps because it has trample or was blocked by more than one creature), the ability will trigger only once.

Dawn of Hope — ruling 2

Dawn of Hope's first ability triggers just once for each life-gaining event, whether it's 1 life from Vicious Rumors or 3 life from Creeping Chill.

Dawn of Hope — ruling 4

If you gain an amount of life "for each" of something, that life is gained as one event and Dawn of Hope's first ability triggers only once.

Dawn of Hope — ruling 5

In a Two-Headed Giant game, life gained by your teammate won't cause the ability to trigger, even though it caused your team's life total to increase.
