Got this from a HP poster named potterwatch in the potterforums:
The 1st killing curse he blocked using the golden statue.
"But the headless golden statue of the wizard in the fountain had sprung alive, leaping from its plinth to land with a crash on the floor between Harry and Voldemort. The spell merely glanced off its chest as the statue flung out its arms to protect Harry."
The 2nd one he dogded
"Voldemort raised his wand and another jet of green light streaked at Dumbledore, who turned and was gone in a whirling of his cloak."
I wonder how he did this though. How he just vanished. Is this apparition or what?
The 3rd killing curse missed
"“By which time I shall be gone, and you will be dead!” spat Voldemort. He sent another killing curse at Dumbledore but missed, instead hitting the security guard’s desk, which burst into
flame."
The 4th he blocked again using more statues which he bewitched to spring to life beforehand.
"Another jet of green light flew from behind the silver shield. This time it was the one-armed centaur, galloping in front of Dumbledore, that took the blast and shattered into a hundred pieces"
We might notice that the statue shattered this time, maybe this is a more powerful killing curse or perhaps the statue is not made of gold like the first one.
The 5th he blocked again, this time using Fawkes
"Another jet of green light flew at Dumbledore from Voldemort’s wand
and the snake had struck. Fawkes swooped down in front of Dumbledore, opened his beak wide and swallowed the jet of green light whole: he burst into flame and fell to the floor, small, wrinkled and flightless."
We might notice that this time Voldemort didnt only shot a killing curse but also used a serpent as diversion. But still managed to block it brilliantly.
