usally 5 years but should be checked monthly
If you change the coolant as recommended in your owner's manual and use the proper coolant mixed 50/50 with distilled water the radiator can last the life of the car. Neglect this service and it may only last 10 years or less.
There is no way of saying for sure. As long as the engine never overheats and you change the coolant every 50,000 miles it should last the life of the engine.
Modern coolants last a long time. I would however drain and replace the coolant every 5 years. Be sure and create a 50/50 mix of antifreeze and distilled water. Do not use tap water.
Yes, as long as you are using the correct coolant as recommended by the vehicle manufacture.

Your anti-freeze is a Dex-cool anti-freeze. It is not compatiable with the green kind. It is a long life coolant which can last up to 100,000 miles. If you have to top off, do not add water as this coolant comes pre-mixed.
Every time you start the engine you are doing damage. The coolant will mix with the oil and coolant is a horrible lubricant. How long you should drive it is none at all. Do not run this engine with a blown head gasket or you will be paying for a complete overhaul or buying another engine.
Shouldn't matter, it will last years.
If the head(s) were checked and had no cracks and the coolant never mixed with the motor oil it could last for many miles depending on how many miles allready on the engine.
"Toyota Long Life Coolant" or equivalent.
It depends on the type. The old green was good for 3 years. There also 5, 10, and 15 year coolants in use.
Yes, if the coolant is still clean and has not been in the system for long. But if you are changing the coolant at the recommended mileage of your cars manual then it should not be reused.
