Please provide real command for PDFfrompng_FILES.
Because there is place where I don't understand you.

I suggest to append these lines to your example to make you need:

PDF_FILES = $(PDFfrompng_FILES) $(PDFfromsvg_FILES)

$(PDFfrompng_FILES) : %.pdf: %.png
        cp $*.png $@

$(PDFfromsvg_FILES) : %.pdf: %.svg
        cp $*.svg $@

and so on for any other file type.
