Yes (assuming the sidewalks/cycle tracks are not mapped as distinct
features, obviously.)

Yes, oneway=yes applies to foot traffic on highway=footway. (It also
applies to foot traffic on highway=path, highway=steps, and
highway=pedestrian -- unless overridden by a oneway:foot tag.)

True one-way foot regulations may be rare, but the data model supports
them. There's been a specific recommendation for oneway=yes footways on
the barrier=full-height_turnstile wiki page since 2017.

Maybe? Depends on the specifics of the hiking trail, and the local trail
tagging norms.

(I also vaguely recall a discussion here about mapping "oneway
recommended" hiking trails, with opinions given on what the tags should
be and whether they might be better on a route relation than on the
individual ways.)

I 'm not aware of any road with two separate cycle lanes that are oneway
in the same direction, but that's the situation described by those tags
(unless oneway:bicycle=no is added.)

No, this would still need a oneway:bicycle=no tag.

IMO it's more accurate & straightforward to say that there's a distinct
and specific set of rules for foot traffic, rather than trying to force
consistency on oneway logic using this "main part of the way" phrasing.

  * For footway: The oneway tag applies to foot traffic.

  * For path, steps, and pedestrian: The oneway tag applies to foot
traffic unless specifically overridden with oneway:foot.

  * For all other highways: The oneway tag does not apply to foot
traffic, but a oneway:foot tag can be used if needed.
