Su-27/33 throttle (both have the same, but you posted picture of Su-33 (cockpit in strong blue color)):
Сброс - discharge (i.e. deploy)
ложные тепловые цели (ЛТЦ) - False thermal targets (i.e. flares)
Дипольные отражатели (ДО) - Dipole reflector (i.e. chaff)
Su-25:
(КЛЕН-ПС) - (KLEN-PS) This is the name of the laser rangefinder in the Su-25.
КЛЕН ПЗ - KLEN FOV (i.e. Klen irradiate) (ПЗ - поле зрения, FOV. FOV, because when you irradiate, the cross moves within HUD glass FOV.)
If you wonder about more, shoot!
