Can huge planets be seen from tiny planets?

Imagine a habitable, water covered, small earth-like orb in space. Let's call it P. From its surface, you see 2 large glowing masses, different sizes, in the sky, let's call them Bs. They are not stars, they are way way too big.

Could these Bs be giant planets, moon, or otherwise satellites that shine down in the night on their habitable neighbor P? Could P be its own planet orbiting the same star as two visible planets, or would an individual planet, by necessity, be too far away to see the Bs as anything but stars?

It would look something like huge moons in the sky, if what I'm asking is possible.
