Regarding chainwheels:

1st one: never seen this pattern before, does not “feel” Swedish to me.
2 one: seen similar types on Swedish bikes, is “neutral” as far as I know.
3.the one in the middle and the left ones remind the of german types. The one to the right looks like a Hermes and later Crescent except for the mounting hole for the crank.
4 & 5: looks American, at least the crank is originating from the Fauber crank, the straight edges instead of a round crank is typical for American crank around 1900-1920`s

Regarding badges:
The badges may be of Swedish origin like Sporrong or maybe german. This design is common and many small makers used them
