In brief: Yes

If you are talking about rem sleep, you can reach it on average in 90 minutes or less.
You can have more deep sleep if you sleep 7hrs straight.

In brief: Maybe

Human growth hormone (hgh) is particularly released during delta phase of sleep, the deepest sleep level.
In an adult, hgh is involved in many pathways involved in maximum tissue and organ performance and minimizes age related breakdown. Remember, it is not necessarily total sleep time but more so the quality and level of delta sleep levels that may be at play.
