Leveling up your City allows you to purchase a second Monkey Village. I forgot which level is required to afford a second Monkey Village, but you could try Buildings (BMC Mobile) article.

If by "second Village" you meant second city, sorry. There isn't an option to unlock a second city on the same account for BMC Mobile.
