I found two names who are the same person when I searched for M. Wajchman. Moryc Wajchman born 19 July 1926 and he lived at Sulzf 18 flat 10 and Lipowa 61. He appears as Moritz Wajchman born 19 July 1924 and living at Sulzf 18 10.
I found Jakub born 20/10/1889 and Rachela boen 06/03/1893 living at thr same address. I'm guessing his parents and I couldn't find anymore information on him or his parents.
