How many people of Arya's list are still alive?

Question

Arya has a list of the people she is going to kill which she starts reciting to herself before bed. Quite a few people from that list are now dead (Especially if you include the Winds of Winter sample chapter from Mercy's POV currently here)

For the people on the list, how many are dead, and how did they die?

Answer 1

At the wiki entry for Arya the following list is given:

Dead

• King Joffrey. Posioned by Olenna Tyrell.
• Ser Amory. Eaten by Vargo Hoat's bear.
• The Tickler. Arya killed him herself at the Crossroads Inn.
• Polliver. Killed by The Hound at the Crossroads Inn.
• Ser Gregor. Died in extreme pain due to the thickened manticore venom that coated Prince Oberyn's spear.
• Raff the Sweetling. Killed by Arya under her guise of "Mercy" at the Gate, a mummers playhall in Braavos.

Alive

• Ilyn Payne
• Meryn Trant
• Queen Cersei
• Dunsen

Removed

• The Hound

Reanimated:

• Ser Gregor a.k.a The Mountain (He was reanimated by the alchemist)

One might add that "the Hound" is sort of dead, at least according to the story of the elder brother of Quiet Isle.

Another interesting tidbit is the prophecy given to Cersei by Maggy the Frog, which implies that Cersei will die by the hands of "the valonqar", which is high valyrian for "little brother". Cersei always thought it was Tyrion, but perhaps it could also refer to a certain "little sister"?
