To replace the spring on a HW57 airgun, first ensure the gun is unloaded and safely de-cocked. Disassemble the airgun by removing the stock, then carefully access the compression chamber. Remove the old spring and clean the inside of the chamber before installing the new spring, ensuring it is properly seated. Finally, reassemble the airgun, ensuring all parts are securely fastened.

Only if the airgun has a scope rail designed into the gun. You will also need an airgun scope not a firearms scope.
You can replace the spring with proper tools. Be VERY CAREFUL a spring that is not caged can inflict serious injury.
There are several ways of making an Air rifle perform better, but most are costly. You could have an air rifle expert "TUNE" it for you. That is have the spring cylinder polishes and the spring either replaced or have it trimmed. The trigger is also another popular item to replaced. All of these can cost as much as the rifle is worth. To locate someone to "Tune" the rifle for you, try the web under "Air gun repair' or "Airgun tuning." One simple way to increase the FPS of an airgun is to put a flat thin sponge in the bottom of your pellet tin, then place a few drops of "Crosman Pellgun Oil' in the sponge. Place your pellets back in the tin and roll them around in the oily sponge. this will lubricate the pellets and they will lubricate the barrel. You will also get a faster FPS and you will notice the difference. Never use regular oil it can damage the seals. Always use Crosman Pellgun oil or RWS pellet gun oil.
you can, but it depends on the airgun. Most spring airguns but two-directional shock on rifle scopes and can wreck them. You can usually get airgun scopes for pretty cheap though. Mostly though, it depends on the gun and the scope.
Crosman still makes replacement parts for this airgun. See the link below
