My friend has a job with the mortuary and says that your pubic hair falls out when you die .Is this true ?

No. The hair on your head doesn't fall out, either.

No. It just stops growing but appears to get longer. I found this interesting:

It is a common misconception that nails and hair continue to grow after death. Neither hair nor nails keep growing once the human or animal has died. It is an optical illusion. What actually happens is after the body dies, it loses water and moisture and dehydrates, making the skin shrink around the skull and skeleton. As this happens, more hair and nails are exposed and make it appear as though they are still growing. Funeral workers will moisturize the body with creams to compensate for this dehydration.
