The short answer is no. The longer answer is, you might be able to get a .40 caliber cartridge to fire from a .45 caliber gun, but it may damage the gun, and even if it doesn't damage the gun, it will cause other problems. In general (with only a few exceptions) you should never try to fire any cartridge in any gun other than a gun designed for that caliber.
No
If you mean a .40 caliber bullet in a .32 caliber gun- no. The bullet would be 8 thousandths of inch too large to fit in the gun. Caliber refers to the diameter of the bullet, so a .40 caliber bullet is ABOUT .40 inches across, and a .32 bullet ABOUT .32 inches across.
