Very good job. I replicated your research, and it definitely illuminates some interesting points. First of all, based on the birth dates and addresses, I believe that you have likely identified Mejlech's parents and sister correctly. Rajzla would have been 33 and Szaja 38 when Mejlech was born. Also, it appears that Rajzla was deported from the ghetto on September 18, 1942. This was a week after the Gehsperre Aktion ended; so, it is uncertain whether she was sent to Chelmno or elsewhere. However, the records for Szaja and Sura record a change of address one month later to a new apartment at Sulzfelderstrasse 14 (ie, apt #20) on October 15, 1942. This raises questions about whether Rajzla's deportation had anything to do with the subsequent change of address for the family (was it a smaller apartment?), and even more importantly, it suggests that Mejlech was probably alive at this time (since he is recorded as having lived at the same address) after all of the major deportations to Chelmno in 1942 had ended!
Keep up the good work, and hopefully you'll find more in subsequent stages!
