going with the "teach a man to fish" motto . . .
1) judging from the color balance of the background lights, i'd say your color temp and tint are accurate. That tells me that if you try to correct for the massive magenta and red shift on the blonde's face, everything else will look blue/green aka cyan. This happens because white balance is a global correction.
2) Bringing the blonde's face back to a "correct" white balance might be possible but would probably hurt the image interest.
1+2 leads me to want to remove some of the cast from the blonde without dramatically altering the rest of the photo, including the back of her head which is in mixed light and not that far from a normal white balance.
I took the posted image (not raw) into PS and went into the Curves dialog. Clicked from RGB to the red channel only and then moved the cursor over the girl's face in the area of the biggest, brightest color cast. Doing this will show you where that color is represented on the curve, notice the line moving around as you click and drag. Then just drop a bit of red out in that area. You will notice this brings the dark end of the red curve down quite a bit. Click one more point to bring the curve back up a little with out making it too dramatic, you almost always want to maintain a smooth curve.
That movement made the image quite a bit darker, so i went back to RGB and brightened it up a bit.
The only other change i made was with Image > Adjustments > Selective Color . . . Choose "Red" if it is not already chosen and drop out quite a bit of magenta, a little yellow and maybe a bit of cyan, in that order.
Give it a shot and post your results and we'll go from there. 
if you take some screen captures of your Curves and Selective Color adjustments I'll critique that too.
