Q:

In The Dark Knight, what happened to all the bank robbers?

The opening scene of The Dark Knight shows a bank robbery being perpetrated by a gang hired by the Joker. It transpires that they are all supposed to kill each other, with presumably each of them thinking he will be the only one left to split the takings with the Joker, but as they are all wearing clown masks you only find out towards the end of the scene that

 one of them is The Joker himself.

The scene starts with five robbers; two on the roof, and three in the van.
One is killed by another after he bypasses the emergency phone call. One is killed after he opens the safe.
One is shot by the bank manager after being tricked into believing the manager has run out of ammo in his shotgun, but is shown alive after that as he says to the other "Who taught you how to count?"
One (this same one) is killed

 by the bus when it hits him, and the Joker then kills the bus driver.

We don't see what happened to the other one. Are there any deleted scenes or transcripts that tell us what happened to him?

A:

For the record, the official screenplay identifies the two men on the roof as Dopey and Happy, the three men in the car as Grumpy, Chuckles and Bozo. 
You've confused Chuckles (whose gunshot was fatal) with Grumpy (whose gunshot was 'superficial')

GRUMPY: He’s got three left?
[Bozo raises two fingers. Grumpy squeezes off a shot. The Bank Manager
  fires. Fires again. Grumpy looks at Bozo, who nods. Grumpy jumps up.
  The Bank Manager fires. Grumpy grunts as buckshot clips his shoulder.
  Falls. The Bank Manager moves in for the kill, fumbling for new shells. Bozo
  stands – shoots him.]
[Bozo picks up the shotgun. Grumpy checks his wound – it’s superficial.
  He struggles to his feet.]
GRUMPY: Where’d you learn to count?!

He was killed by the bus coming in through the front of the bank

GRUMPY: Bus driver? What bus –
[Bozo steps backwards. Smash. Hostages scream as the tail end of a
  yellow school bus rockets through the front of the bank, slamming
  Grumpy into the teller’s window.]

For the avoidance of doubt.

Happy shoots Dopey on the roof
Grumpy shoots Happy in the vault
Chuckles is killed by the Bank Manager
Grumpy is killed by the bus
Bozo presumably kills the unnamed bus driver
Bozo survives
