If you mean how many types of warning, on all these aircraft there are visual, audio, and tactile warnings. The visual is flashing stall warning lights, the audio is warning clackers and voice warnings, and the tactile is stall warning shakers that vibrate the control column in the pilot's hands.

The system itself differs from aircraft to aircraft, but typically there are 2 computer systems that each use data from 2 angle of attack probes and 3 air data sensor systems to calculate stick shaker and stick pusher thresholds. The shaker/pusher signal will have to be verified by another system in order for the system to actuate the control yoke.
