I think it will be limited stable if it has two poles only lies on JW-axis and have no real poles lies on negative real axis, now if it exists (poles on negative real axis) then it will be underdamped oscillation which is the stable case.

But if poles are repeated on jw axis then the system is unstable, right?

Your answer is right @Rc Kashyap.

When it lies on left of jw axis then it is known as stable.
When it lies on right of jw axis then it is known as unstable. When it lies on jw axis then it is known as limitedly stable or marginally stable.
When it lies on right of jw axis then it is known as unstable. When it lies on jw axis then it is known as limitedly stable or marginally stable.

Limitedly stable.
When it lies on left of jw axis then it is known as unstable.
When it lies on right of jw axis then it is known as stable.
When it lies on jw axis then it is known as limitedly stable.
When it lies on left of jw axis then it is known as unstable.
