you mean totals for the week in general?
theres some controversy around Time Under Tension as a weekly guide, maybe someone here has an opinion? as for per session, it’s probably highly individualized, but there is some convincing research that 45m staves off going catabolic. seems to work even if doing an am/pm split. 45m each. I feel best if i keep it under an hour stretching included.
3-4X per week doing each muscle group hard once every 5-7 days is ideal
lifting everyday is going to wear your body down as you age. you can get away with 5-6X a week training when you are young, but it won't work later in life trust me
It depends on your goals. If you are just doing it to be healthy then 3 days per week is fine. If you have a goal such as adding lean muscle or losing fat then I would recommend 4-5 days per week. That goes for both natural lifters and guys that use PEDs.
