Thye smith&wesson model 28-2 was chambered for the .357 magnum cartridge.I would say Start with the one round that you and the gun shoot best.Then you can experiment on different weight bullet loads.You may also shoot standard .38 special loads in your model 28.
Needs to be examined by a gunsmith.
You have a Smith and Wesson model 14 38 special. The 38 refers to the diameter of the barrel. That barrel is 38/100 of an inch in diameter. A 45 automatic has a barrel that is 45/100 of an inch in diameter. A 9mm has a barrel with a 9mm diameter. You can shoot 9mm ammunition from a 38 special. A 22 pistol has a small diameter barrel.
You need to find a firearms instructor.
.32 rimfire Smith and Wesson model 2 1/2
The gun is likely a Harrington & Richardson (H&R) model 925. The caliber is .38 Smith and Wesson (S&W) special, not to be confused with .38 special (SPL). You must shoot the .38 S&W ammo, not .38 spl.
Depending on what it is choked, yes. Have a gunsmith examine it.
You must follow the instructions in the owners manual or call S&W
