Oh, dude, Pinkamena Diane Pie is a character from the animated series "My Little Pony: Friendship is Magic." She's known for her energetic and party-loving personality, but also has a darker alter ego named Pinkamena, who is more serious and introverted. So, like, she's basically a pony with multiple personalities - talk about drama in Equestria!
No. Pinkamina Diane Pie is simply Pinkie Pie's full name. Some of the fans use Pinkamena to refer to Pinkie when here hair goes straight, which we see in a flashback to when she was a filly and when she is depressed. The idea that this variant of Pinkie is evil stems from the horror fanfiction "Cupcakes" in which Pinkie Pie tortures and murders Rainbow Dash.

Well, from the episode The Cutie Mark Chronicles, we are shown that Pinkie has two sisters who are later named Marble and Limestone (fan named Inky and Blinkie) but it mentions in a My Little Pony book that Pinkie also has another sister. An older one who remains unnamed at the moment. Some fans of the show also have rumored Peachy Pie as her sister though this will probably never be confirmed.
