Switch wiring for 2 single pole switches and 2 different lights
To make one switch the master switch, and always function one light:
Connect power to the inlet side and the outlet side directly to the light.  That light will always function with the master switch, regardless of the other switch position.
To get power to the other switch, run wires from the outlet side of the master switch (can use the push slots, or wire it with twist caps) to the inlet side of the closet switch. Then run wires from the outlet of the closet switch to the closet light.
