Fully charge the battery with a slow charge battery charger. Then take the battery to an auto parts store and have it tested. If it is over 4 years old it is probably in need of replacement.

Can you charge a dead battery by getting a second car that is running take the good battery out of the running car and put the dead battery into the running car as a means of charging it?

No, this will place a very heavy load on the alternator of the car and may result in burning out the diodes of the car charging the battery. You could easily ruin the alternator. Purchase a battery charger and charge the dead battery with that. Alternators are not made to charge dead batteries.
