An ability that triggers "whenever you gain life" triggers just once for each life-gaining event, no matter how much life you gain.

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, Scion of hte Swarm'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.

If Scion of the Swarm is dealt lethal damage at the same time that you gain life, it won't receive a counter from its ability in time to save it.

If you gain an amount of life "for each" of something or "equal to the number" of something, that life is gained as one event and Scion of the Swarm's ability triggers only once.
