The diamater of a 9mm parabellum bullet is 9.03 millimeters, or .356 of an inch.
If you mean 9mm Parabellum (also called 9mm Luger)- no. the 9x18 (Makarov) is fatter and shorter than 9mm Parabellum. It is not a true 9 mm.
It depends on the bullet weights. The 9 mm (AKA 9x19 mm, 9 mm Luger, or 9 mm Parabellum) is faster than the .380 ACP (AKA 9 mm Kurz) except when you compare the lightest .380 bullets to the heaviest 9 mm bullets. If you compare the same bullet weights in each, the 9 mm is always faster.

Yes. .38 special is a revolver cartridge and .380 is an auto cartridge. Also, the .38 will almost always have a heavier bullet and more muzzle energy than a .380. The .38 bullet is 0.357 inches in diameter while the .380 is 0.355 inches in diameter. Technically, the .380 cartridge is considered part of the 9 mm class of bullets. [9 mm x 19 mm = 9 mm Luger or 9 mm Parabellum, 9 mm x 18 mm = 9 mm Tokarov, and 9 mm x 17 mm = .380 ACP]
Both Glock 17 9 mm and beretta 92 fs witch are butter because of their high durability.
The diameter of the the two bullets are just about the same, but the length of the brass case which holds the bullets are slightly different. The Makarov's case is 18mm long, while the Luger's (Parabellum) case is 19mm long.
It's the length in millimeters of the entire cartridge. A 9mm para is 9 mm in diameter and 19mm long. Additionally, just for reference, it isn't referred to as 9 times 19, it's 9 by 19.
