It is not age but pounds for a child seat. Check with your DMV, but I think it is over 40lb.
The age in which a child can stop using a car seat or booster seat varies from state to state. In Michigan, the child safety seat law says that a child under the age of eight years old must be in a safety seat unless they are taller than 4' 9.
in all states a child has to be 4foot nine to be out of a booster seat. they can be in a booster sear at any age.
The Booster offers safe, comfortable rides for someones child. Moving from a car seat to a booster seat still helps the child remain safe, while riding comfortably in the booster seat.
When they are around 2 and have outgrown their child seat. They should continue to use a booster seat until they reach the height of 4 foot 9.
the weight to sit in a booster seat is...40 pounds AND the age of 4 years, BUT preferably the child is longer.
Do this to check if a child can leave a booster. The child should place their back on the seat with their big ass in the end. If the child's feet can touch the ground they are ready. Most children stop using booster seats when they are 7.

Yes you have to.
yes
If your talking about the booster seat without a back then NO, It is not safe for the child to ride with only a lap belt.

An air bag can severely injure of kill a young child if they are not old or big enough to be sitting in the front seat. Car seat safety varies by state, but once the child outgrows a booster seat, he or she is permitted to ride in the front seat with a seat belt around the age of 13.
