Given the birth date, designation as a student/schueler, and the name similarity, I believe that you have correctly identified Szmul Sandler as Samuel Sandler. Note, however, that the Lodz Ghetto Database provides two entries with slightly different birth dates for Szmul. One also includes a middle name (ie, Szmul Ber Sandler). The alternate birth date is three days off the one you have entered... 25/01/1926.
