Would it be correct to say that there is a definite, finite value of time constant in a Resistor- Capacitor circuit, i.e is there a constant value for RC ( where R is resistance and C is capacitance)

Yes, there is a definite RC time constant for any given resistor and capacitor. There are also other time constants for real components, related to stray inductance, skin effect, and sometimes mechanical resonances.
The as-marked R and C values are valid characterizations of the physical objects only in a broad sense; no object is purely a resistor or capacitor, though resistive and capacitive behavior can be good approximations in 'normal' circumstances.
