A comprehensive magnetic and superconducting phase diagram determined by muon spin rotation/relaxation ($$mu$$SR) is presented for Ca$$_{2-x}$$Na$$_x$$CuO$$_2$$Br$$_2$$ which has apical bromine atoms. Evidence for antiferromagnetic (AF) order in lightly doped samples and that for quasi-static spin glass (SG)-like state in moderately doped ones are obtained by ZF-$$mu$$SR at low temperatures. While the phase diagram is qualitatively similar to that in typical 2-1-4 cuprates including Ca$$_{2-x}$$Na$$_x$$CuO$$_2$$Cl$$_2$$ and La$$_{2-x}$$Sr$$_x$$CuO$$_4$$, it exhibits a slight shift (expansion) over the $$x$$ axis.
