Answer:
ok this is a hard question to awnser but here it goes. in the first three books there are seven vampires edward, carlisle, rosalie, Emmett,jasper, Alice,and Esme. then after WARNING THIS IS A FULL SPOILER Bella gets pregnant with renessme And because she is human almsot dies during the birth of that child, so basically edward gets venom into her system and she turns to a vampire so now there is eight vampires. Edward and Bella, Carlisle and Esme, Jasper and Alice, Emmett and Rosalie, and of course the half vampire renessme Edward and Bella's biological daughter.
