Just take a look at countries where they have a working bike infrastructure like Denmark or the Netherlands and adapt it your your country. (Also, separated bike lanes)
Yes, outside the cities and villages, where the number of pedestrians is low and that of cyclists often not large either. In those situations sharing infrastructure generally isn't an issue.
Inside cities and villages, I don't think I've seen roads with a bike path, but without a pedestrian path. Maybe I've seen one in an industrial park or so.

I see this situation all the time. Does every single bicycle underpass under the motorway have a full sidewalk alongside it? I can point to many situations in the Hague, Utrecht and Rotterdam where the bicycle path is the only option for pedestrians getting from point to point. I also know of tunnels that have bicycle paths but no pedestrian path. The only way to get across as a pedestrian is to use the bicycle path.
Yes that is true, but most of the time this happens in places where only a few pedestrians are likely to use it. I can count on one hand the amount of times in the last few years that I have needed to walk on a bike path as a pedestrian while working in Amsterdam and visiting many other cities and towns.
It happens I agree, but as far as I can tell there are few places in the Netherlands where more than the occasional pedestrian need to walk on the bike path for more than a few meters.
Combined walking- and biking-paths are the norm here in Sweden. Granted maybe we don't have enough big cities for it to be a problem, but Ive never really heard complaints about it. These "roads" are generally fairly wide, so its not really a problem with 4 "lanes": pedestrians and bikes going each direction.
