It is lawful and right to keep the name Muzayyan. It means decorated. It is also lawful to keep the name Mazeen. It means: person with beaming face (Taj al-Uroos 36:169 published by Kuwait Govt.)
And if you keep the name Muzayyan then it is far better as it is the name of the father of an Ansari Badari Sahabi as well as the name of the grandfather of an Undulusi Maliki Faqih. (Taj al-Uroos 36:173)
However, the most beloved names to Allah are Abdullah and Abdur Rahman, as it is mentioned in hadith.
Allah (Subhana Wa Ta’ala) knows Best
Darul Ifta,
Darul Uloom Deoband
