This question is extremely complicated. First of all, if your definition of a fan is a person who watched an liked Star Wars, then Vader is the last sith lord. However, Vader turned to the light side, so if this makes him not sith, the sidious was the last sith lord.
In the expanded universe, the first sith lord who came after Vader was Darth Cadeus, aka Jacen Solo.
If your definition of a sith is a person who uses the dark side of the force, then there are the witches of dathmir, the prophets of the dark side, and the emperor's hands.
The first Sith Lord who came after Vader was actually Palpatine again in his clone bodies.
And before Caedus (Caedus is the correct spelling) there was Dark Lady of the Sith Lumiya who converted Jacen Solo to the dark side.
No , Darth Vader is part of the Star Wars universe .

Darth Sidious cannot be the Pope as he is a fictional character from the Star Wars universe. The two individuals just happen to share an unfortunate similarity of physical appearance when viewed from some angles.
