Relating? I assume that means either dating or having sex. In the case of dating, when ever you want. In the case of sex, when ever you are capable of dealing with the possible consequenses...so when mom and dad arent supporting you anymore.
there is not a right age to start dancing but the best age to start is 2/3 years old.

Whenever she feels ready to start her career for her older age maybe a young age!:)

As soon as possible.
As young as possible.
Nothing
Well it depends on how mature you are. Also if you want to go to the Olympics I would say start around 4. If not maybe 7-10 would be best. Remember you can start a sport at any age.
There are no age limits to start ballet as each studio differs but it is best not to start too early, six is a good age to start at if you want to be a professional ballerina
5-7 years old
8-10 years
As soon a possible! Stay fit!
