If a charge q was placed inside a cavity inside a metal shell, then inside this shell would there be any electric field??

And since Gauss law says that this metal surface would have an induced charge then a point within the regoin between the cavity and the outer surface of this shell thn would there be any value for electric field at that point?

There will be no electric field within the conducting materials but there will be an electric field in the void and external to the conductors. The reason for zero field within the conducting material is that, statically, it would have led to an infinite amount of charge build up due to current flow.
