Depending on where you are, questions 1 and 3 are just straight up illegal. No interviewer in the US would dare ask about vices or your family situation unless they don’t mind shelling out lawsuit settlements to everyone they interview and decline to hire.
I actually saw a job application recently asking to confirm that you haven’t used any nicotine products in 6months in order to be hired. This was very strange as it was a 100% remote job so maybe it was HR/copy paste but the wording was bizarre . They made it clear that it was about nicotine and not just tobacco and explicitly called out things like gums or patches.
I did not continue the application. I assume now it was some useless virtue signaling related to young people and vapes or something. I’m not even sure they’d seriously test people, but it’s still ridiculous that according to what was written you could be denied employment or lose your job because you had a cigarette outside the bar last weekend or have been using nicotine gum to quit smoking
