Questions:

1. If in install app which uses system permission like "android.permission.CHANGE_COMPONENT_ENABLED_STATE" than what this app will be automatically goes to system folder?

2. If i install app which not uses any system permission than what that app will also goes to system folder or it will install as normal application?.

Answer 1

if you install app using the normal way, that is , use adb install or install from your device.

1. No, the app will be at /data/app
2. it will install as normal application

Root will not grant all app root privilege , nor change the install routine.

you can just take root as putting a su binary in your /sbin, thus your app can spawn processes as root, such as execute a shell command as root.
