The most common way to describe two people who are married to each other is to say:
Married couple.
All the married couples had name tags.
Sometimes two people may be together but no married, that would be called:
A couple.
They had been a couple for years.
It can also be called:
An item.
They were an item.
This is an informal way of saying that two people are going out with each other (boyfriend and girlfriend or fiance's). It normally means they are not married yet.
I hope that helps!
