We are tried to count how many files belong to certain group. Our system administrator told us "non-owner" can easy change file group name to another. I have been tried several combination and never successful (only ROOT can change file group to other name).

Does anyone know how "no-owner" can change file group name?

If the "no-owner" user has write access to the file they could copy the file to a new file name(thus getting ownership of the file), and overwriting the original file with the new file.

You need write access in the directory, but only read access to the original file to do this.
