1. Make note of this one:

Cracking Knuckles

Cracking one's knuckles in good health doesn't cause arthritis or other issues. The cracking sound comes from a gas bubble forming when the joints separate.

5. Which is caused by what exactly?

If the joint is pulled apart slightly, the fluid can no longer fill the space and a vacuum bubble will form. This will make a noise when it collapses. The process is very similar to cavitation in propellers that move liquids.
