1 is all over the place depending on what your car has; my wife's car has lane keeping and blind spot monitors and those live in a knockout panel down and left of the steering wheel.

2 I've usually found in the buttons near the shifter

3 I'm not sure what you're referring to? If it's the little screen generally between the speed and battery/rpm display those controls are usually on the steering wheel in my experience.

4 Steering wheel, in every car I've seen it in and that's often standard across the models

5 This one I've only had one experience with and that's my wife's Kia Niro EV and those are on what would be shifter paddles in a car with a gear box.

The number of buttons on steering wheels between my decade old gas Golf and my wife's few year old Niro EV are shockingly similar though presented and arranged differently. Both have 4 buttons and two directional pairs (audio control for skipping on one, volume on the other, cruise control speed on another and one dimension of the hud paging on the last) though the Niro has the pairs as rocker switches that can click for one extra button I suppose.
