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.

Check your alternator (it charges the battery) If it quits you are running straight off the battery and that won't last long. Also check your belts. If they are loose and slipping your battery won't get carged and your alternator won't work properly

As long as the battery is fully charged it will start no matter the condition of the alternator. Eventually the battery will run down if the alternator is not keeping it charged.
How long do you run your car after a a car jump?
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.

Have replaced alternator twice on 1999 zx2is this common?
Depending on how long the interval was between alternator changes. Less than a year and I would look for warranty on the alternator. Now there are factors beyond the alternator manufacturers control. A battery that is on it's last legs will take out an alternator really fast. A stereo system with a large Amp(s) will also shorten the life of an alternator drastically. These situations will not be a warranty issue.
Why is your 1981 ford F150 starting without an alternator?
You don't need an alternator to start your engine only to recharge the battery. You could start any vehicle without an alternator but that doesn't mean it will run for long. Newer vehicles would just run till the battery was drained.
