Can they wear Copper rings?
yes a muslim man can wear anything except Gold and Silk
Sure they can. But why would they wanna? Copper rings make your finger turn green.
Copper, brass, and iron or metal are clearly discouraged in the hadith. Imam Nasaai and Abu Dawood record the following hadith in their books: Buraidah (radhiyallahu anhu) narrates that a man came to the Messenger of Allah (sallallahu alaihi wasallam) wearing an iron ring. The Messenger of Allah remarked: Why do I see on you ornaments of the people of Hell? The man then discarded this ring. After some time he again came into the presence of Rasoolullah (sallallahu alayhi wasallam), this time wearing a ring made of copper. Upon noticing this the Messenger of Allah exclaimed: Why do I get the smell of idols on you? The man dsicarded that ring, too. He then said: O Messenger of Allah! Whatype of ring should I wear? The Messenger of Allah replied: Wear a ring of silver but let it not amount to a complete mithqaal (approx. 4,374 grams).
Why not? Except gold they are permitted to wear all the metals!
