Great work on the uniforms. Some I see are inspired by Osprey Men at Arms Frederick the Great´s Army
Allright grenadier 2nd from left top left is IR15 Leib Garde Batallion 3.
Musketeer top right last one is IR15 Leib Garde Batallion 1 also a grenadier though they wore tricornes.
The grenadier left from IR15 Musketeer is Pomeranian Provincial Corps grenadier
Or actually more specifically it is Frei Grenadiers Hullesen and Wüssow two batallions that were frei corps in the Swedish SYW army
Prussian frei grenadiers but they fough for the Swedes in Pomerania against Prussians.
The musketeer at the bottom with light blue pants can be any frei corps but Le Noble comes to mind
Uhm not to be nitpicky, but correct me if I am wrong. The musketeer in the middle bottom line has drummers lace on the arms. Looks more like a drummer actually except the actual drum. I have not seen any regular infantry in the Prussian army that wore drummers lace except just drummers and fifers
