I don't have a problem asking personal questions, but I am very private and feel that others ask them of me all the time. I find most questions invasive unless they're obviously impersonal.
Looking at your list of questions I was thinking that questions about things people do in private or alone definitely fall into that category. That includes anything without clothing (sex, things one does in the restroom, etc.), or doesn't openly talk about first, such as account numbers, salary, etc. I was taught that you generally don't bring up politics and religion because people feel so strongly about them and discussions can get heated very quickly when you talk about them. I also feel that except with very few people, that sexual habits are also inappropriate to talk about.
Sometimes at work the whole clucking lot of them will start talking about sex which I find very off putting. So I suppose it depends on who you're with. If they bring it up first, maybe the topic is acceptable, but if the person you're talking to seems to get quiet or fidgety, maybe change the subject. Following someone else's lead in conversation may help.
