The transfer function of the system is stable as it is seen in the figure? The denominator includes the exponential term is a violation of Routh Hurwitz criterion. I also did not draw the unit step response of the system. How do we implement a stability test for this system in Matlab? (BIBO, Lyapunov, etc.)

You can make a linear approximation of those time delays (Exponentials in the frequency domain) using the Pade Approximation:
Once you have your linear systems, you can just look at the poles of the system to determine (approximate) stability.
