Need to specify a specific type of firearm. There are many, many firearms manufactured for various 9mm cartridges, and a lot of variation as to how many rounds they can hold between them.

I think you mean bullets, not builts- and that varies from one machinegun to another. Some hold as few as 10, some use a belt of cartridges that could be any length.

In a factory.
The common 9mm cartridge is known by many names. All of the following 9mm's are one and the same: 9x19mm, 9mm Nato, 9mm Luger, 9mm Parabellum. There are no 9mm cartridges specific to Glock or Smith & Wesson.

Well there are many different BRANDS of ammuntion that you can buy for a glock. but obviously you will need 9mm bullets for a 9mm gun.
Perhaps the most common 9mm CARTRIDGE is the 9mm Parabellum- commonly called the 9mm Luger. And it IS for an automatic pistol (and carbine and submachinegun). However, there are probably a dozen or more OTHER "9mm" cartridges- many fairly scarce- such as the 9mm Makarov, 9mm Browning Long, 9mm Kurz (the .380) etc. They are different and do not interchange.
No. There are more than a dozen DIFFERENT "9mm" cartridges, and they do not interchange. The most common is 9mm Parabellum- also known as 9mm Luger or 9x19. It does NOT interchange with 9mm Kurz, 9mm Corto, 9mm Makarov, 9mm Ultra, etc.
No. There are several different calibers that are called 9mm. These calibers are not interchangeable. A quick rundown of 9mm pistol cartridges: 9x17 also called 9mm Kurz, 9mm Short or .380 Auto 9x18 Makarov, also called 9mm Makarov 9x19 also called 9mm Luger, 9mm, 9mm Para, 9mm Parabellum 9x21 also called 9mm IMI 9x23 also called 9mm Long, 9mm Largo
Neither one exists, so there are no differences. However, there is a cartridge known as the 9mm Luger. It is chambered by many makers in pistols. Ruger is one of them.
9mm MKV is not the same as 9mm Luger.
