Impossible to answer as it depends on use and abuse. Normal use will see no need to replace one on a modern car.

It depends on just how 'bad' the alternator is, but generally, not very long. You can actually drive your car until there is not enough electrical charge to spark across the spark plugs, and your car just stops, unable to start again.
yes the engine runs the charger/alternator as long as the engine is running the battery should be chargeing
Yes, as long as the engine is running, so is the alternator. The alternator is actually what keeps the car battery charged.
As long as the battery is kept charged then it should last 3-5 years.
depends how long you use them
Battery will be flat because spark plugs were running straight off your battery because the alternator was not charging your battery as you were driving. You can test this by jump starting your car with another car and after your car is running you should be able to disconnect your battery and car should still run off the alternator. If your car stops than your alternator is RS. Battery will be flat because spark plugs were running straight off your battery because the alternator was not charging your battery as you were driving.

for a very long time
Car batteries last four to five years on average.
As long as the battery is charged
I assume you mean how long to charge the battery. You should never let the alternator charge a dead battery if possible. The alternator is designed to keep the battery charged but not to charge a dead battery. You put a strain on the alternator and it can cause a diode to burn out. Drive home and then put a battery charger on the battery to fully charge it.
As long as the ignition switch is off, it will not damage the alternator.
