Capacitor charging and discharging status
If yes, when will the capacitor be re-charged again? Will be it charged after the long exponential charge decay of the capacitor or will it start to charge itself after it has a certain amount of charge left? Will this process of charging and discharging be continuous if the switch S remains in closed position? Let me start with some basics.

If, by "while it is in use", you mean while the capacitor is discharging, i.e., energy is flowing out of the capacitor to some load, then the answer is no since, by definition, if a capacitor is charging, energy is flowing into the capacitor. Put another way, a capacitor cannot be both charging and discharging at the same time. Either, the ...
