The first two signatures do not look remotely similar to me. Look at the M’s just to start with. The M’s start in a different place and are constucted entirely differently, although the same pen seems to have been used, which one would expect if signed at the same time. The third signature is with a different thicker ink and is unintelligible to me, unlike the previous two.

I agree that the beginning letters are different but if you are forging then the beginning is foremost on your mind. If you look into the body of each signature the angles look like they all fall into the same slant.
