Yes! The gravitational acceleration depends on the mass of the things involved and the distance between them. The moon has less mass than the earth so you weigh less there as there is less force pulling you down onto the planet – this is why you can make massive jumps on the moon.
If you did spend a lot of time on the moon you’d grow a little bit as the gravity is less, but when you got back to the earth you’d shrink again. You’d also take a while to adjust as you have to work less hard to move on the moon, so your muscles will get weaker. When you got home, you’d have to go to the gym a lot to try to build them back up!

Yes, on the moon you weight about 6 times less than on Earth — that’s why you see the astronauts on the moon making such big jumps!
If you spend a long amount of time in space, I believe that your spine will become looser because of the lack of gravity — so yes, you will become taller (a bit). But then you get back to normal when you go back to Earth. This happens to astronauts who live for long periods of time on the international space station.
