Several potential reasons that your battery is not charging. It could be that your battery is too old and must be replaced. Alternatively, the electrolyte in your battery is low and that you have damaged your plates by not replacing the lost fluid with distilled water. Thus, you may have to replace your battery. Or, as you suggest, it could be a defective alternator (actually voltage regulator in the alternator). However, first you should check the belt your alternator runs off. If may be loose, causing the alternator not to charge the battery. Old belts develop multiple microcracks that will loosen the belt tension. Have you replaced your alternator belt since you purchased the vehicle (about every 50,000 miles)? If your belt is tight, it could be that your alternator is bad. Brake light could be related to alternator issue, or you have a separate problem with the brake fluid sensor. Remember to check your brake fluid at least monthly. Hope this helps.

Yes, because a bad coil will not allow the engine to run. But if the engine is running then the coil has nothing to do with the alternator charging the battery.

No. The alternator has to be turning to produce the charging voltage. It only turns when the engine is running.

Why is the car battery charging at 14 volts running and 13.5 not running?
your alternator charges the battery while the car is running. The alternator actually puts out a higher voltage than 14 volts while it is running, but it is reduced by a voltage regulator (most of which are already built into the alternator housing), to prevent damage and premature death of the vehicles battery. While your car is not running, the alternator is not charging the battery, and the 13.5 volt reading you get is just the measurement of the voltage the battery is holding at that given point.
How do you tell if the alternator needs replacing?
With the car or truck running disconnect only the positive side of the battery ... if it stays running that means the alternator is good if it dies then it needs replacing
