It depends on the muzzle speed produced by the particular brand of ammo.
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.
Generally speaking, the .45 caliber bullet is larger in diameter and heavier than a 9mm bullet.
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.
It depends on several factors, but it can be a slow as a few hundred feet per second to a couple of thousand feet per second. The average for the most common types of ammo is somewhere about 1000 feet per second.
Yes
The .380 ACP is also known as the 9x17mm, 9mm Short, and 9mm Kurz. It is the ONLY ammunition which can be fired through a .380 pistol. The 9x18mm Makarov (whose bullet diameter is actually 9.3mm) and the 9x19 Parabellum/Luger cartridges ARE NOT compatible.
Technically speaking- none. A bullet is the solid metal part of a cartridge that is fired out of the barrel. How much gunpowder is in a 9mm Parabellum CARTRIDGE will depend on the powder used and the bullet weight. I reload with 4.6 grains of Bullseye powder with a 115 gr bullet, but there are dozens of other loads.
I'm assuming you're asking if a .380 round can be fired in a 9mm handgun. The answer is, yes, it may be possible, but it is not a good idea to fire any cartridge in a gun other than the correct caliber for that specific gun.
Technically, a 9mm bullet has NO energy, since the bullet is the metal part that leaves the muzzle of the gun when fired. However, the 9mm Parabellum cartridge does have energy. The exact energy varies with the loading of that cartridge- but about 420 ft lbs of energy at the muzzle. Typically this is more than a .38 Special cartridge, less than a .357 Magnum cartridge.
Maybe 1700 miles per hour - but it depends on the gun and (especially) the amount of powder used.

9mm and .380 bullets are the same diameter. In fact, .380 is also called 9mm Kurz(short) or 9x17. However, the caliber commonly called 9mm is 9x19, which means the cases are different size. A .380 cartridge will fall down into the chamber and the firing pin will not reach the primer. So, a .380 bullet can be fired from a 9mm gun if it were loaded into a 9mm case. A .380 cartridge would fail to fire in a 9mm gun.
380 and 9mm projectiles are .355 in diameter _________________________ Most of the time, when people use the term 9mm, they are referring to a 9mm parabellum. A 9mm parabellum cannot be fired from a .380. The 9mm cartridge is longer. _________________________ The BULLET is the part of the cartridge that is the projectile. While 9mm parabellum and .380 ACP use the same diameter bullets, the CARTRIDGES are not interchangeable.
A single 9mm bullet is about 3-6 cents. A 9mm Parabellum (Luger) CARTRIDGE is about .30-.55.
Generally speaking, the .45 caliber bullet is larger in diameter and heavier than a 9mm bullet.
