It depends on your state's laws.
It is legal in Florida for a 17 year old to date a 21 year old.
In most places, a 25-year-old dating a 17-year-old is not legally allowed due to age of consent laws.

Yes and legally as well. in most places. NO.

Yes.
No. The age of consent is 18.
Legally, No!
No. It is considered sexual abuse. A boy or girl at 11 years old is too young to date and they are a minor not mature enough for a girl 17 . A 17 year old girl needs to date someone who is her own age.
No, and no.
Dating is not illegal. Having sex is illegal.
