Since you discovered that Luba Estera Hecht was actually the married name of Luba Estera Epsztajn, I decided to perform a search on Luba Epsztajn (which found nothing new) and Estera Epsztajn (which found some useful data)! Because Estera Epsztajn was born on November 27, 1928 and she also lived at Sulzfelder Strasse 15 Flat 2, I believe we can conclude that these two girls are the same person.
