No, you must have a charged battery for the alternator to work.
Here's an explanation of how the charging system works:

If the alternator is in good condition, it should provide a charge to the battery while the engine is running and it will recharge if the battery is also in good condition. The act of starting the car actually discharges the battery.
All the time
The Battery? No, not typically the battery. That means that the alternator is not charging the battery and IF the engine is running, it's getting all of it's electrical energy from the battery. It means that once the battery charge is depleted, the engine won't run again until you recharge the battery.
Yes, a loose battery cable will prevent the alternator from charging the battery. The drain on the battery is not caused by the engine not running unless an accessory is left on. Most likely, the drain is caused by accessories (radio, lights, etc) while the engine is running due to the battery not receiving its charge from the alternator and then not having enough charge left to start the engine.
There could be many reasons why the engine has no spark. A few reasons could be that the starter or starter solenoid is going bad, or the battery is drained.
if your alternator is gone or going your car will start and then eventually just stop running because your battery has gone dead. it typically will not make any sound when your engine is not running because of a dead battery.
Yes, the battery starts the engine, and as long as the battery is fully charged the engine will start. The battery will loose it's charge if the alternator is defective and not replenishing the charge of the battery but the alternator has nothing to do with starting the engine.
If the engine is running and the alternator is good. If the engine is not running, no.
No, they discharge. The alternator recharges the battery when the engine is running.
yes the engine runs the charger/alternator as long as the engine is running the battery should be chargeing
provides electricity to keep the engine running, recharge the battery, and operate such equipment as lights and radio

Jump start car and do not run heater with engine not running.
The alternator is connected to a gas powered engine. This charges the battery.
If the battery is fully charged and the starter is working properly it will turn over and start. The alternators sole purpose is to supply voltage to the vehicle and battery when the engine is running. When the engine is not running the alternator has nothing to do with starting the engine. If the alternator went bad and the battery was discharged then you will have to charge the battery before it will be able to start the engine. Do not jump start the engine with a dead battery if you can avoid it. This puts a strain on the alternator trying to recharge a dead battery and can damage the alternator, even a new one.
The purpose of an Alternator is to periodically recharge the battery while the engine is on.

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.
Maybe the battery is defective. Check the voltage at the battery terminals with the engine running at idle. You should get 13.5 to 16 volts. If not the alternator is defective or the voltage regulator is bad. If you are getting the correct voltage, the battery is bad or the connections are corroded.
