Confusion regarding Apple USB Power Adapters

Hi,

I currently have...

1 x iPhone 5

1 x iPhone 4

2 x iPad 2

The power adapters I have are...

1 x A1402

1 x 1357

2 x A1205

Could someone please advise me what charger is associated with each device? The reason I have asking this is because my girlfriend owns the iPhone 4 and one of the iPad 2 and she has 2 of the chargers at her house. I want to make sure each device has the correct charger with it.

Cheers
