Answer 1

Given a collection of members and a given total ordering, a member is in the `n`th percentile if it’s “greater than” or equal to (under the definition given by the total ordering) `n %` of the other members.

So for example, for a given set of requests and their latencies, a request is in the 95th percentile (p95) if its latency is is greater than or equal to 95% of other request latencies. And we say the p95 latency is the cutoff at which that occurs.
