as ghosts, and only for a couple minutes in the seventh movie. in the book it's a whole chapter.

No, they have been dead since the first book.
No, they do make a reappearance of sorts, but they are not resurrected.
jk Rowling liked the name harry and the potters were a family who lived in her street.
Nobody can come back to life if they die, not even in Harry Potter. His parents, Sirius and Remus sort of come back but they aren't fully alive.
He was a student at Hogwarts, also the Youngest seeker in the game of Quiddich and eventually the undoing of Voldermorts attempt to come back to life.
Harry bought it in Ollivander's wand shop when he was eleven. The wood is holly and the core is phoenix feather.
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.
Just as ghosts for a very short time.
His parents come back in spirit form twice. Once in the Goblet of Fire, one in Deathly Hallows part 2. In the Goblet of Fire his parents come to help him hold Voldemort so he can escape, near the end when he and Cedric find out the cup is a port key. In Deathly hallows part 2 his parents appear when he is going to present himself to Voldemort to die. He uses the resurrection stone, which is hidden inside the first golden snitch he caught, to view them, Sirius and Remus. He asks them briefly what it is like to die, and they have a short conversation.
