Most CD changers can hold four discs, but some can hold up to ten at one time.
Depends on what kind of "discs" you're referring to... (compact discs? brake discs?)
Most CD changers hold between 5 to 10 discs, but there are models that will hold up to 12 discs.
A 72-disc changer is available by special order from Rockford-Fosgate.

If it is the standard audio system (NOT the MACH with CD changer), press and hold down the "CLK" button while pressing left or right on the "SEEK" or "TUNE/DISCS" buttons. (One does minutes up and down, the other does hours up and down)

a cd player is designed to hold and play only 1 cd at a time where a cd changer can hold multiple cds and will let you select which cd to play. you will have to remember which cd is in which place in the player
You can indeed make Blu-Ray discs that hold 35 GB of data or more.
Most multidisc dvd players hold around 3-5, however there has been word of some "mega disc players" that can hold around 300-400 discs! No-one knows if these actually exsist, but while we're waiting to find out, a normal disc player that holds up to 10 discs should do the trick.
Any, you just need to get a CD changer box and attach it to the car and cd player. The Pioneer 12 Disc Capacity Multi CD Changer holds the most.
