Can i use "at home ipl hair removal device" on: a)shaft of penis , b)testicles , c)genital region, d)on the skin on top of adam's apple, e)neck?

Check directions: Please read instructions carefully. I don't know this device - but many will specify areas that it should not be used on.

No for genitals: Do not remove hair from your genitals. It is likely to cause more problems than whatever it is that you are trying to address by removing hair. Have a healthy diet, exercise 30 minutes/day, drink plenty of water, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/. Get HPV vaccine. Wish you good health!
