That is an extremely vague question. A .357 can run from a couple of hundred dollars to several thousand depending on what it is.
Between 250-450 dollars,depending on the overall condition from good to excellent.
100-1000+ depending on specifics
No, you should not fire .357 ammo in a .38 Special gun as the .357 ammo is longer and more powerful, which can be dangerous and damage the gun.
Your gun is a 357 and can shoot both 357 ammo and 38 special ammo. The nice thing about these guns is you can practice at the range with 38S bullets, which are much cheaper, and save the 357 ammo for home defense.
If the weapon is chambered in 357 Magnum, you can fire the round in it.
