A 9mm Parabellum cartridge loaded with a standard bullet and only a primer will normally not be able to drive the bullet out of the barrel. It will usually lodge in the barrel (this is known as a squib load). If a second normal cartridge is fired behind this, it stands a very good chance of blowing up the gun.
A primer will usually get it out of the case.
None. Bullets generally do not contain gun powder. You may be thinking of a cartridge. Bullets are just chunks of metal.
9mm
The .380 is a 9mm bullet. But, going with the assuming that you're comparing the .380 ACP (9x17mm) against the 9mm Luger/9mm Parabellum (9x19mm), the answer would be no.
DRT ammo. Frangible round, a fine powder surrounded in copper. 9mm,40 s&w,5.56 nato,308 winchester. Made by Dynamic Research Technologies. Nickname "dead right there". It will go through a door, but will not go through a body. When the bullet hits a ballistic material it explodes and the powder goes into everything in about a 5" radius.
None. A primer does not contain propellant powder- it contains an explosive that ignites the powder. If you mean how much propellant powder is in a 9mm cartridge, that will depend on which 9mm cartridge (there are nearly a dozen different 9mms) which weight bullet, and which powder. My basic reload data table for 9mm Parabellum (9mm Luger) is 3 pages of data with different powders, bullets, etc. A basic load is 4.5 grains of Bullseye powder with a 115 grain bullet.
A round is a cartridge made up of the case, primer, powder and bullet. The bullet is the projectile that leaves the gun. There is only one bullet in a round.
Depends on which powder, and which loading of the 9mm.
Small - regular - not the magnum
9mm Parabellum cartridges (9mm Luger) HAVE small pistol primers. For some applications such as submachine guns with a free floating firing pin, a harder primer may be used. However, in most applications, the same primer used in .38 Special would also be used in a 9mm.

A primer will usually get it out of the case.
Usually just a primer will get it partway down the barrel.
The 9mm Lugar round is longer than a .380 Caliber, which is also equal to 9mm in diameter. The overall cartridge and the bullet is larger and the case contains more powder. The 9mm Lugar is more powerful. BTW, the .40 cal Smith and Wesson is also called a 10mm. It is only 1mm larger in diameter and a little more powerful than a 9mm Lugar.
Less powder for its size.
A 147 grain 9mm bullet can travel between 750 and 1,000 feet per second, depending on the powder charge.
No. They are the wrong diameter, 45 you need large pistol/large rifle sized primer diameter. Also rifle primers are thicker and require a heavier primer strike that some pistols can not deliver. My Springfield XDM only intermittently can set off a small rifle primer when used to load 9mm.
