Yes, you can.
It is not recommended to use a 12 volt charger to charge a 14.4 volt battery as the charger may not provide enough voltage to fully charge the battery. Using the correct voltage charger will ensure efficient and safe charging of the battery.
No. You can only charge one 12 volt battery at a time or two 6 volt batteries wired in series at a time if you want to use that 12 volt charger.
No, a 12 volt charger will overcharge a 8 volt battery and destroy it.
If you can get the battery to run the motor, write it up in a science journal. You'll be rich. Sure but what are you going to use to power the 12 volt motor? You will have to use another battery which you could just use to power the radio in the first place.
no it can't
No, the battery is DC not AC.
