Your research so far looks accurate, the other J. Ajlenbergs are born too early to have been children in Lodz during the deportations. Although JewishGen does not list his occupation as a student, we can assume this because of his age. If you continue your research, you might want to look into the possibility of Jakob being deported to Chelmno, since Chelmno deportations occurred during his recorded deportation date of February 23, 1942.
