Does Lightsail count inbound and outbound data transfer?

Both inbound and outbound traffic count toward the allowance, but only outbound traffic beyond the allowance is charged as overage.

Which Lightsail instances share a data transfer allowance?

Instances of the same bundle size in the same AWS Region pool their allowance. Dual-stack and IPv6-only instances of the same size pool together.

No. Overage already incurred is still charged, so add instances before the pool runs out.

It depends on the Region, from $0.09 per GB in US and most EU Regions up to $0.17 per GB in Sydney.

Uses the rule that same-region, same-size instances share one transfer pool to find the cheapest plan for elastic traffic.
