The System is unstable,
Since, the pole at z = 0.4 lies inside the unit circle and the other pole at z = 2 lies outside the unit circle.
For a system to be stable, all the poles must be inside the unit circle in the z-plane.
Therefore, the system is unstable.

H(z) is actually z transform. Now finding the ROC:
The roots are 0.2, 2.
which makes a circle that encloses the unit circle, so the system is stable.

Find ROC by using partial differentiating it gives two poles both are causal so the greatest pole is roc that means z>2, should lie outside the circle. It is unstable.

The ROC for the non causal signal is? Can anyone answer this?

According to me, it is Unstable.

What is Roc?
If we use control systems topic here.
The system is stable because all poles are lying on the right-hand side.

Pole is Z=2.

Pole is Z=2, the unit circle is 1. So it is unstable.
Then how, it should be stable? Explain it.

All poles are in the left half of s plane.
So, Use the concept of control system.
So, Use the concept of control system.

The system is unstable since the pole z=2 lies outside the UNIT circle.
