Probably. We never hear anything to the contrary, at least.
It is unknown as they remain unnamed.
No it won't if they remain faithful to the book.
In the book there are explosions which would lead to fires but Hogwarts was still standing and everybody could remain inside. In the film however, there is a promotional poster which shows Hogwarts burning so quite possibly it burns in the film.
The stone is the Resurrection Stone, one of the three Deathly Hallows (the other two being the Invisibility Cloak and the Elder Wand). It can bring people back from the dead, though not completely; they remain detached because they do not truly belong. It is hidden in the snitch that Dumbledore leaves Harry in his will, though it is in two halves as it used to be a horcrux, but Dumbledore destroyed it.
Technically speaking, yes. But as long as there are those who remain loyal to the books, and the movies, it will never truly end. The next generations will definitely grow up with Harry Potter as well, because the next generation will have the story passed on to them - just as we've had old stories passed unto us.
In Harry Potter once someone is dead, they remain dead. Nothing can bring them back to life. James and Lily Potter, Srius Black and Remus Lupin all return to Harry in a spirit form when he holds the Resurrection Stone. When he lets go, they go. Harry also met with Albus Dumbledore in his 'limbo' area.
In the Deathly Hallows Snape was the Headmaster of Hogwarts and seemed to be a Death Eater. Near the end of the book, Harry witnesses Snape dying. He goes to him and Snape gives him two memories in a glass vial. The first memory is Snapes way of telling Harry how much he loved Lily Evans. The second memory is him talking to Dumbledore and agreeing to be a double agent and remain faithful to Dumbledore.
James is in Gryffindor Albus who is leaving for Hogwarts at the end of Deathly Hallows WANTS to be - and is scared he will be in Slytherin Lily is too young for Hogwarts at the end of Deathly Hallows
Harry Potter and the Deathly Hallows follows Harry, Ron and Hermione on their quest to find and destroy the rest of Lord Voldemort's Horcruxes and eventually end the wizarding war.
Potter wasps create elaborate nests with many cells. The adult wasps lay eggs inside these cells where they remain until the larvae hatch.
That would be impossible to determine and wouldn't remain the same.
He becomes headmaster after Dumbledore dies, and hires Death Eaters as professors. In Harry Potter and the Deathly Hallows, he is the owner of the Elder Wand, and is killed by Lord Voldemort, in order to gain ownership of the Elder Wand. Severus Snape was not evil. He worked for Dumbledore, as a spy, and gained the trust of the Death Eaters and Lord Voldemort, without them realizing he was against them. Dumbledore asked Snape to kill him so Draco did not have to, so Draco's soul could remain whole. Snape also helps a cursed Dumbledore, by encasing the curse to his right hand.
