I got 5 files, how to use them with Odin?
AP : CODE, CP: MODEM, BL: BOOTLOADER (you dont seem to have that), CSC: CSC or HOME_CSC and USERDATA: USERDATA same for when you need to wipe the user data. I your case you'll only need 3 files AP, MODEM and CSC/HOME_CSC which contains your carrier specific files, settings etc.

Note that the firmware you are trying to flash need to have same version than your current version on the device or higher, otherwise you'll get the error you are getting in your third screenshot.

Important: Do not use the pit file as it repartition the internal memory and can cause a brick, and actually it is the cause of the flash failing message, so it is not advised to use it.
