Depends on the amperage you are applying to it. Read the charger manual.
Yes, but it will take a very long time if the battery is dead.
It would depend on the condition of the battery.
The car battery has 12 volts; you need MORE than that to charge it. You can't charge it with 6 volts, unless you somehow raise the voltage. In that case, how long it takes to charge the car battery will depend on the capacity of the charging device. Usually a few hours.
14 hours approx
I charge my battery 4 hours and 30 minutes

A trickle charger is a car battery charger that is designed to be left on a car for very long periods of time to re-charge that car battery by slowly adding charge to the battery.
No, because if it is frozen it will not take a charge.
As long as both batteries are the same voltage, you can jump start with the battery. If you want to charge the battery then use a battery charger.
If your leads are long enough, yes.
Depends on how low of charge the battery is. I would guess around 6 hours on a dead battery. I suggest you use an automatic charger so you do not have to guess.
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.
