From wikipedia:

A “vicar” is, roughly, a representative. In the Catechism of the Catholic Church, in addition to the pope, each bishop is referred to as the “Christ’s Vicar”(§1560) to their diocese, and the conscience is called “the aboriginal Vicar of Christ.”(§1778)

And one level of pastor in the Anglican church, besides rector, is vicar.

I’ve never heard the title applied to anybody but the Pope.
