"Are there any other members of your family in the city?" or Do you have any other family members in this place?
## whoever you have in the city ##
"any other members of your family living in this city"
## we are about to destroy ##
The word "we" here is exclusive. Only the two angels would destroy the city; Lot would not destroy it. If your language has an exclusive form of "we," use it here. (See: [[rc://en/ta/man/translate/figs-exclusive]])
