The proper noun Athens is the name of a city. It would not ordinarily use a plural. It might be possible to describe Athens (Greece) and Athens (Georgia) as "two Athenses" or simply as the "two Athens."
The Greek singular is Athene (person of Athens) and the plural is Athenai -- so it is the city of the Athenians, or Athens.The modern name of Athens (Αθήνα, Athína) is now singular in Greek, since the monotonic form of the Greek language was adopted in the 1970s.
Athens was a polis. It didn't contain other poleis (plural of polis), though in the Delic-Attic League they did dominate many others.
There is no English word "athen" but the proper noun Athens is a city in Greece, as well as in US states including Georgia.
