In the pidTuner menu, there are two displays to the right of Response Time and Transient Behavior sliders that change the numerical value showed. What do they exactly indicate?

They indicate the response time (in seconds) you choose with a "response time" slider and transient behavior number you choose with transient behavior slider.
If you are asking what the numbers mean, then the first defines how fast your system is, the second one how stable.
If you are familiar with bandwidth and phase margin concepts, then the the first number is 2/bandwidth, and the second number is phase margin.
Bandwidth here means 0dB gain crossover frequency of the open-loop response.
