Hey, ok so i downloaded Disgaea The Hour of Darkness and when it says its done I "Open folder" and then it says a "RAR" file and i need to make it NDS obviously so i dont know how to make it an nds file so i need a little help

You need to extract it with Winrar. Go to win-rar.com to download it, install it, right click on the game extract and then you can play either on the emulator you downloaded or on a flash cart if you have.
