Toggle battery powered LEDs
This should do it. SW1..SW3 are the contacts for positions 2,3,4. 

R1 to R3 control the brightness of D1-D3 yellow LEDs, if you increase them also increase R4 proportionally. 

R5 controls the brightness of the white LED.

If you have a double pole rotary switch rather than a single pole, you can lose the transistor and R4 and just tie the second set of contacts to R5 to turn the white LED on whenever the switch is not in the 'off' position.
