No, the dead is dead, food good.
Yes, one of the two is.

No. The only other time Dumbledore is in the Books is in the 7th book. But he is not alive.
Dumbledore does appear, he is not exactly alive, but he is in it as his individual character and does talk to Harry.
When Lord Voldemort asked Dumbledore for a job, he was still alive.
Nobody can come back to life really. We see a few characters again but none of them are alive. Dumbledore talks to Harry as does his parents, Sirius and Remus.
Yes. in the 7th book. but as a ghost. kinda.
Answer: Sadly, he is dead, and even if he were alive, he would never use a computer. Answer: Please note that Dumbledore (and most other characters from Harry Potter) is a ficticious character.
We see him again but he isn't alive. He meets Harry in a sort of limbo. Harry can chose to die or go back (because he isn't fully dead only the part of Voldemort inside him is) and Dumbledore talks to him there. Harry asks if it is all in his head and Dumbledore answers: "Of course it's happening inside your head, Harry, but why on earth should that mean that it is not real?"
No. He won the wand from Grindlewald, who was still alive during Deathly Hallows.
Dumbledore's greatest fear was finding out who actually cast the spell that killed his sister Ariana. It was either Dumbledore himself, his brother Aberforth, or Grindlewald. I believe it was Grinldelwald because he fled the country after her death and Dumbledore never saw him again until their legendary duel in 1945. Dumbledore's reason for delaying his meeting with Grindelwald was because he was afraid he would find out the truth.
Michael Gambon played Dumbledore in Harry Potter. Ian McKellen played Gandalf in The Lord of the Rings and will do so again for The Hobbit.
