Thanks - good advice. Sadly, though,not all of the figures are labelled. FN175 / FNFN 194 / FN 195 seem to be just described as "stragglers" and so a reference guide might be helpful in identifying them.
Much obliged for the suggestion!
I don't have the packs in question but most of the figures depicted in the photos appear to be line infantrymen, with the occasional dismounted cavalryman thrown in for good measure.
The frozen casualties (pack 195) are no longer wearing any kind of identifiable uniform and can be painted pretty much as you want.
Pack 194 features an infantry flank company private on the left, what appears to be a hussar stealing a blanket from a dying line or light infantry officer (the standing looter is wearing a hussar pelisse), an infantry grenadier 'liberating' the shoes from a dead infantryman (either line or light infantry since he is wearing a greatcoat and can be both) and finally a light cavalry trooper (judging by his sabre), most likely a
chasseur à cheval :

The three stragglers on the left and the second from the right in pack 175 are line infantrymen, while the one on the far right is either a cuirassier or a dragoon (I'd say cuirassier but it's hard to tell from the helmet in such a small pic) while the third from the right wearing a fur cap is a cavalryman - possibly a dragoon judging by his coat and buttoned cavalry overalls :
