No absolute answer, other than as long as possible, to allow to set, dry and cure. Can we assume the walls have now been decorated, therefore a period of time was allowed for plaster to dry out? If so, should be fine to drill in to now.
The drying time will depend on the depth of basecoat applied (if not boarded).
It is important for the plaster to be allowed to dry fully, as decorating over this will cause paint to fail, flake and blister and wallpaper not to adhere.
Any furniture or pictures/mirrors, put up against these walls, will also trap in moisture.
There is no real given time, as there are a lot of variables, concerning plaster depth, surface applied to and drying conditions.
I would never try to force the drying though, just keep the area dry and warm.
6 weeks is often given as a rule of thumb, prior to painting. I would say with regards to the drilling of holes, that a weeks drying would be sufficient.

if it is still moist, it will tend to grab the drill, then you will have to patch the hole.
i think a week or two, if on dry old brickwork. Damp brickwork can take months. If you are suspicious, start with an undersize drill
Use a matt, non-vinyl emulsion such as Dulux Trade Supermatt, once the surface is uniformly pale pink with no brown patches. keep the windows open and it will not take long. Supermatt is not very durable but is porous and will allow the wall to dry out through it. Thin the first coat or two with water so it soaks in.
When the wall is fully dry, you can paint or paper over the supermatt with a more durable finish.
