Phone Version&uninstalling Google Apps?

Aug 12, 2017
Hello new user here, with a redmi note 4 waiting for unlock.
I have two questions how do I know which version of redmi note 4 I own? My dev romance ota updated to miui9

Is it possible to Uninstall unnecessary Google apps? Like duo, play movies, hangouts, etc. Because they come pre-installed and I don't use those services.

Best case scenario I'd like to have Google play only.
