You normally should meter with all the lights on. You point the bulb at the camera and usually hold the meter beside the face of the subject. Now if you want to determine ratios, you meter each light separately, but all fire together. Point the bulb at the hair light for example. Use your hand if needed to shield the bulb from another light. That gives you the info for the ratio. Same for a fill light --- use the hand to shield from the main.
I do it differently myself. I use the Photovision Target to zero in on the exact exposure and then use the meter if needed to determine power of background light, hair light, etc.
Re: Metering strobes - together or separately
For spill control, shoot a test shot, look at where the spill is, and then use flags to control or feathering.
