Edward Cullen has many vampire "siblings" because they all kind of "adopted each other," but as far as before he was a vampire, it is not said whether or not he had siblings. His vampire siblings are Rosalie, Emmett, Alice, and Jasper.
When they are in Forks, they are: -Carlisle Cullen -Esme Cullen -Edward Cullen -Emmett Cullen -Alice Cullen -Jasper Hale -Rosalie Hale But technically they are: -Carlisle Cullen -Esme Cullen -Edward Masen -Emmett Cullen (It doesn't say his human last name at any point in the books) -Mary Alice Brandon (Alice) -Jasper Whitlock -Rosalie Hale
He's not shy. He is trying not to kill any human that he is around because he is a newer to the Cullen family.
No he was an only child in his human life.
Yes he does in twilight eclipse and Breaking Dawn
He has a little sister
To not have any emotions or be immune to Jaspers empathy.
