The Bahai Faith does not have a Pope. The Bahai community is administered by elected counsels, called Assemblies or Houses of Justice. The local and national Assemblies are elected every year. The head of the world-wide Bahai community, the Universal House of Justice, is elected every five years.
Doctrines are not decided by the Assemblies: they are based on the writings of Baha'u'llah and the explanations of them from two authorised interpreters: Abdu'l-Baha and Shoghi Effendi. There is no authorised interpreter today, and none can be appointed (Abdu'l-Baha and Shoghi Effendi were appointed in Bahai scripture).
The Black Pope's birth name is Shelly Pope.
Since Pope Francis is the first and only pope by that name, there is no need for a number after his name. If a pope in the future also decides to take the name Francis, he will become Pope Francis II and then the original Pope Francis will become Pope Francis I.
