Planet P has two moons with different orbits. Do they display the same lunar phases at the same times? Is it possible to have moon A waxing and moon B waning in the same sky viewed from P's surface? Google wasn't very helpful. I thought I'd find info about Jupiter or Saturn's moons.

Lunar phase is dependent on the relative position of the moon, star, and planet, so no, no two moons would be in the same phase. Assuming they were sufficient distance apart, you could have one moon in the latter parts of the waning phase while another has proceeded into the waxing phase, yeah.
