| ftp://pricepages.org/temp/N044W124.cal_s.png

| N044W124.or.png N044W124.id.png N044W124.png
|

YES  compose only does TWO images, and a optional mask!

Try a convert with a mosaic operator

  convert  N044W124.cal_s.png N044W124.cal_n.png \
           N044W124.or.png  N044W124.id.png \
           -mosaic N044W124.png

If the first image defines the final size use -flatten instead.
