My guess is you have PS broke (you're not honoring the embedded profile?).
First turn PS's colormanagement ON, and see if the files are tagged...
If they are not tagged, then you will need to ask the originator what his/her WorkingRGB is (and PS> Image> Mode> Assign (that profile).
If the originator is unavailable (or clueless), I would try PS> Image>Mode> Assign (the profile that best corrects the image) -- then edit the file into shape.
Either that or return the job...
TIP (to get the red lower):
PS> Image> Adjustments> Selective Color (Red, add 5-20 Cyan to start)
PS> Image> Adjustments> Hue/Saturation (Red, minus 10 to start)
