Hi Bruno,
May I suggest you upload future images to JewishGen's dedicated image translation/interpretation site?
They don't upload immediately, but they stay there for a whole week - and all responses there are public, giving everyone a chance to contribute and learn,
ViewMate - Image Gallery (jewishgen.org)
ViewMate - Instructions (jewishgen.org)

As for the new images:
The name is Aharon son of the honored rabbi rav Shim'on.  The next characters - last in the first line of the first image, first on the second line of the second image look like a stylizes z"l to me = i.e. "may his memory be blessed" and indication that at that time Rav Shim'on was no longer alive.

The next word if "from Hellringen" or something similar.  The ending "n" or "en" could have something to do with the name in German - we are after all in Alsace Lorraine here....
