Dont quote me on this, but...
The first one looks like an ambiant temperature sensor (For measuring the cabin temp of the car).
The second looks like the Sunload sensor (For working out how much sunlight is hitting the windscreen)..
The third looks like a standard small size wedge lightbulb with a blue condom over it. (Dunno why this is there, as holden uses LEDs exclusively in the VE instead of these 0.5Watt bulbs)
The fourth I have seen before (Its simply a link / resistor connector, but not sure what its for or where its from, but it places a resistor value in line with the socket).
The lasy image is the wiring loom itslef
