When we discuss performance of a distributed system we use the terms tp50, tp90, tp99.99 TPS. Could someone explain what do we mean by those?

tp90 is a maximum time under which 90% of requests have been served. Imagine you have times: 10s 1000s 100s 2s. Calculating TP is very simple: sort all times in ascending order: [2s, 10s, 100s, 1000s] find latest item in portion you need to calculate.
TP99 latency is the minimum time meeting requirements of 99% requests. In APM, latency refers to TP99 latency. Example: Assume that there are 100 requests, and the time consumed by the requests is 1s, 2s, 3s, 4s... 98s, 99s, and 100s. To meet the requirements of 99% requests, at least 99s is required.
The PBS TP100 is a turboprop engine, which is ideal for small aircraft and unmanned aerial vehicles (UAV's) and is particularly suitable for use by the rescue services, the police, the military (for reconnaissance purposes) and in agriculture.
