There is no such currency
Since zen is not a monetary unit, the country is fictitious. Sen is a monetary unit of Brunei, Cambodia, Indonesia, and Malaysia, equal to one hundredth of a dollar in Brunei, one hundredth of a riel in Cambodia, one hundredth of a rupiah in Indonesia, and one hundredth of a ringgit in Malaysia. It is also a former monetary unit in Japan, equal to one hundredth of a yen... with a "y."

No, you cannot trade in a Zen mp3 player for an iPod Touch. A Zen mp3 player is only worth around $10-$15, while the iPod Touch (any generation) is worth over $100+.
I am not aware of any country town or village that begins with the letters "Zen." It is possible that a place with this name exists, but it may be challenging to locate as it is not a common prefix for place names.
The plural of "zen" is also "zen." The word "zen" does not change in the plural form.
