Yes, Galileo's laws are true anywhere in the Universe, but the laws of falling bodies and the pendulum are specifically related to motion within a uniform gravitational field, such as on Earth or on the Moon.
As a matter of fact, for the first time in histroy it was on the Moon that it was demonstrated that a hammer and a feather will fall to the ground at exactly the same time if they were dropped from the same height, thus proving Galileo's law of falling bodies is definitively true (because there was no atmosphere on the Moon and therefore no friction and no air currents to disrupt the feather from falling to the ground at the same time as the hammer.).

like Physics Dude said, check out:

"At the end of the last Apollo 15 moon walk, Commander David Scott (pictured above) performed a live demonstration for the television cameras. He held out a geologic hammer and a feather and dropped them at the same time. Because they were essentially in a vacuum, there was no air resistance and the feather fell at the same rate as the hammer, as Galileo had concluded hundreds of years before - all objects released together fall at the same rate regardless of mass. Mission Controller Joe Allen described the demonstration in the Apollo 15 Preliminary Science Report"

yes!!!! because as the law states that two or more bodies falling in to the ground they must reach equal to the ground neglecting the effect . therefor in the moon there is gravity then the law can also apply on it.

Yes, they are true throughout the Universe, they are laws of Physics that apply throughout the known Universe.

Yes. Newton's 3rd law demonstrate that.

They would be true in and place where there is a measurable gravitational force. So any of the planets or stars would do.
