I am trying to build a quadrature hybrid coupler with arbitrary power division which is a 4 port network. I need to see the power at the 2 output ports to realize my design. How can I plot power in HFSS just like we plot the S parameters?

Is there some reason S-Parameters aren't sufficient for your purpose?

Yes, you can integrate the normal component of the Poynting vector over the port's surface to get the total power travelling into/out of the port.

One way would be to insert the HFSS design into a circuit design, and there you can plot the output power.

However, in HFSS if you know the input power set at the input of the hybrid (value set in excitation/edit sources), and if you know the attenuation of the hybrid (atenuation given by the simulator), by subtraction you can find the output power at the output of the hybrid. Plotting would be a bit time consuming.
