It depends on how mature the 9 year old is. I would say yes, but only for a couple hours. And make sure he/she doesn't try anything dangerous.
12-13 years old, and can only stay on their own for a few hours.

13 years
Absolutely NOT!!! No matter how responsible, 16 years old is not an appropriate age to stay home alone for that amount of time.
No, you have to be around 15/16+ to stay at home with a younger sibling/relative.
10 or 11 you can stay for 2 or 3 hour's
