Yes. it is possible. You might be in pain though. In order to make you're dimple you must poke something threw your cheek i.e. Knife, or get it pierced etc. It is more effective to get it pierced.
no it is not possible for you to loose your dimples
yes it is because your cheeks are cells
You can't really MAKE dimples. Dimples are completely genetic.
It depends on the manufacturer. Each company has their own dimple pattern.
Dimples make the ball aerodynamic and allows it to fly with stability. Without dimples the flight of the ball would be very unpredictable.

Poke your cheeks
These are called dimples, they make the ball aerodynamic, without these dimples a ball could not fly.
Not necessarily, dimples are a dominant gene and if neither you nor your spouse passed it on, the baby will not have dimples. The chance of your child not having dimples is probably 1/4. However, if BOTH your parents have dimples, it is possible there will be a 100% chance of the baby having dimples. It's complicated. Basically there is a three fourths chance of dimples.
They make the ball more stable and aerodynamic.
This would depend on whether the allele for dimples is dominant or recessive. If the allele for dimples is dominant and the no dimples allele is recessive then the phenotype of the individual would be dimpled. If the allele for no dimples is dominant and the allele for no dimples is recessive then the dimples will not be expressed. If these alleles are codominant then the dimples will be expressed but not as much as in an individual who has both alleles for dimples.
They allow the ball to fly, and make it aerodynamic.
