Everybody is different once it comes to sleep. Most researchers agreed upon 8 hours asleep at night time is healthy as long as the quality of sleep is good.

Absolutely correct. Some people need more sleep than others. Anywhere between 2 and 10 hours.
As an adult 6 to 8 is normal but not a requirement.
Opinion only: Different people have different sleeping requirements. If six hours of sleep is close to your normal or average sleeping habit and you feel fine, I see no harm in going to the gym on this one occasion. If during your exercises, you feel weak or tired; simply return home and sleep or try to relax.

As a person gets older they require less hours of sleep and can actually function better on a lower number of hours. Typically when you get older you have a harder time sleeping and only get about 4-6 hours of sleep a night.
