Anything that is on and uses electricity. You may also have a dead cell in the battery which will drain the battery.
no , only the concrete and other cemented floors ....
A dead cell in the battery will cause it to loose it's charge overnight. The only fix is to replace the battery. Any light that is staying on will drain the battery. Also a stuck relay will drain the battery.
Follow the positive battery cable from the battery, the other end is connected to the starter.
Have your battery and altinator tested it is possible that one or the other was bad from the store, if they are both ok then you have a drain somewhere in your electrical system somewhere, any shop with diagnostic tools should be able to trace the drain for you.
Indirectly. The positive cable on the battery is hooked to the starter. The other wire on the starter post goes up to the alternator.
Follow the positive battery cable from the battery down, the other end will be attached to the starter.
Year, make, model and engine size would help but if you follow the positive battery cable from the battery to the other end of it, it will be connected to the starter.

While possible, usually not. More probable is some other load remaining on. Places often missed are glove box, trunk, and engine compartment lights.
only if the car your using to charge the other on is not started
Corroded battery cables. Other than that you probably need to remove the starter and have it tested.
You have a bad cell in the battery and a bad cell will drain the other cells. get another battery
