I am going to answer this in a round about way, cause well I'm not sure there is a difinite group of questions I ask. To me I ask them as I need to, although some most certainly like to know all before. I ask questions that I need to know to advance my plot, and make my charachters real, and I look at all the things other people don't need to know, but I do this to understand my charachters world, their motivations, and to be able to give them logical responses for their time to answer the questions and problems they face.
I ask and try to answer all those questions you listed but I don't normally feel the need to tell the reader them all. Some yes, but the answers that I see the reader needs to know are those that advance the plot. I am not debating your questions below, but how I decide if I use the informatin I found when searching to answer those very questions.
Eg. I mentioned my MC had plaits...those plaits got pulled later.
Eg. If I have a certain occupation mentioned...it is relevant to the plot...no use mentioning someone is a lawyer if I don't need a lawyer, unless maybe I am trying to show a different social circle.
Eg. What they sleep on, to me is only important to mention in the story if it has a part to play in advancing the plot...eg it's their matrominal bed, it catches alight, it's uncomfortable to sleep on when I have to put my charachter on it.
I think some exceptions can be made in some of the things I just said, possibly to add a bit of colour, but colour that does not have a purpose is a bit of a waste of time. Use it if has a purpose, but not for the purpose of a filler. Slight difference.
I don't think we need to know how someone went to the toilet, unless maybe a body is going to be found in the pit. Or while they are going to toilet something happens to advance the plot...the bad man breaks in or something.
We don't necessarily need to see someone clean themselves, unless maybe what they clean themselves is with is important to the plot or shows us it is hot or apart of their charachter or something.
We most certainly need to know how the air felt, but only in a manner that would seem odd to them...throughout history certain societies did not bath and in turn the bad body odour we smell today, they would not have...actually it may have arroused them. Some races in ancient times put animal manuer, or more so annointed their genitials for this purpose.
With metaphors and smilies I think this belongs to a different question... but what they imagine or dream, or see in their everyday life that they compare as in.... it was as bright as a...or it was like a ... the thing to remember is that they can only use one that is true to what they know...an MC in the 1700s can't say - I ran as fast as a plane... It hit me like a rocket launcher...ect
The most burning and important questions to me are if the sentences I have or want to included are true to the time period. If in doubt I research more.
I seek to find evidence that what I have included is possible for that time. That my charachters reactions and responses to something are possible...and that if I decide to mention they use leaves when going to the toilet, it is needed to advance the plot, and more importantly that the reader needs to know that because it is important to the story, not because I need to impart knowlege of what I have learnt.
