Tapping your nails can be a harmless habit, often serving as a way to relieve stress or pass the time. However, if done excessively, it might lead to nail damage or discomfort in your fingers. Additionally, the sound can be distracting to others in quiet environments. Moderation is key to ensuring it doesn't become problematic.
A few examples of bad habits one might have are the following: nail biting, tapping nails rudely, interrupting others talking and eating excessive chocolate.
biting your nails. It wears down your teeth and you have more germs under your nails than anywhere else, and your letting those germs enter your mouth.

It depends on what's tapping. You may have a bad lifter or a valve problem.
In some cultures, cutting nails on Friday is considered bad luck.
Theoretically increasing bloodflow to the ends of your fingers should increase nail growth. (Within reason; once you reach a certain amount of bloodflow to your fingers, increasing it further will have very little impact upon nail growth). So tapping your fingernails may increase bloodflow, but it seems likely that you may also chip your nails doing this. Touch-typing, knitting etc... should have the same impact upon increasing bloodflow, and may also prove more productive than tapping your fingernails. (I personally find that knitting really strengthens my nails).
