3: when we go to Settings > More Networks and manual setup i receive list of operators which are available in my country so any way to find what their signal strenth or DBM is i mean any app is available or any way .
Regarding unlocked and rooted. You should know when a phone is rooted you can't get any OTA updates. If you want to upgrade you will need to do it via Odin from PC. In the general section there are a couple of threads pinned that will help.
