The first two are Danish and the third is Norwegian local town mail. The 4th is also Scandinavian but I do not know from which country. Looking at the language and the image I think Danish railway parcel post but I do not even know if such stamps exist.
They are Scandanavian -- Norwegian and I think there may be a Danish one in there.
Sorry I don't have the proper catalog as they are not listed in my FACIT. Maybe somebody has a Schoyen & Aune or a Pihl catalog; those are 2 of the major Norwegian Local Post catalogs.
If you can read German, there's a pretty good website on the Bypost stamps:
