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.
Where else but at Hogwarts?
Snape
In Order of the Phoenix, Professor Snape teaches Harry Occlumency and Harry's least favourite, Potions.
He attempts to teach Harry occlumency. Occlumency is keeping your mind closed (from people trying to read your mind or otherwise invade your thoughts)

The opposite of occulumency is legimency
Probably Lily Potter, whom he loved throughout their childhood
He took Astronomy, Care of Magical Creatures, Charms, Defense Against the Dark Arts, Divination, Herbology, History of Magic, Potions, and Transfiguration. Later in the year after he had the envision into the attack of Mr. Weasley from Nagini, he got private Occlumency lessons from Prof. Snape.
Focus is the spell that stands for this spell.
Tobias Snape is Severus Snape's father.
He loved Lily Evans (Harry's mother), but she only considered him a close friend. She was his only real friend; they had become friends as children. Snape's love for Lily - in spite of her marriage to James Potter, whom Snape despised - was his motivation to become a double agent for Dumbledore when he learned that Lily was marked for death by Voldemort.
