No. Voldemort kills Snape before the battle is over. But even if Snape had survived, Harry would probably have testified on his behalf, and told everyone how Snape was really working for Dumbledore the whole time. In fact, Harry did say something to that effect, out loud so everyone could hear, during his final duel with Voldemort.
Yes. In the Half-Blood Prince Snape killed him. Draco Malfoy was supposed to do it, but he could not do it, so Snape had to. We find out in Deathly Hallows that Snape and Dumbledore had planed the entire thing.

This is a very broad question, and not worded correctly. Severus Snape killed Albus Dumbledore in the end of the sixth book. Dumbledore had asked Snape to kill him, to save Draco Malfoy's soul because of the Unbreakable Vow that Narcissa Malfoy made Snape take in the beginning of the sixth book since Voldemort had ordered Draco to kill Dumbledore.
Professor Snape uses the Avada Kedavra curse against him at the end of The Half-Blood Prince. This was a pre-arranged deal between Snape and Dumbledore, as we learn in Harry Potter and the Deathly Hallows-Dumbledore preferred that Snape kill him since he knew death was coming and he wanted it to be painless. He did not want to have to deal with getting attacked by Fenrir Greyback or getting tortured by Bellatrix Lestrange.
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.
No, Snape loved Lily Potter (Evans). Harry's mother.
Snape killed Dumbledore because: 1. Dumbledore was already dying. 2. Dumbledore asked Snape to kill him. 3. If Snape didn't kill Dumbledore, Draco would have had to and Dumbledore didn't want Draco's soul ripped apart on his behalf. 4. Snape made an Unbreakable Vow with Narcissa Malfoy that he would kill Dumbledore if Draco failed to do so. 5. It would land Snape firmly in Voldemort's good books so that Hogwarts would be under the control of Snape and not the Carrows. 6. If J.K. Rowling hadn't killed Dumbledore somehow, the final battle would be postponed for too long.
the reason why Snape killed Dumbledore was for Dumbledore not to protect harry so that Voldemort could proceed to kill him.
No, Snape's soul wasn't damaged, because Dumbledore had told Snape to kill him.
First, Professor Mcgonagall. Then Snape.
The real answer is that Snape was on Dumbledore's side, so he killed Dumbledore on Dumbledore's orders. He has been a fake servant to He-Who-Must-Not-Be-Named.
