Question

delta H will be positive as heat will be released from changing its state from gas to liquid.

delta S will be negative or of less positive value the randomness in the physical state is being reduced as the molecules will be coming from higher entropy gaseous state to liquid state.

delta G will be positive because delta H and delta S *T will both combine to give more positive value.

As delta G = delta H - delta S *T

W will be positive as W = P* change in volume. As the net volume is positive hence work done will be positive too.
