Found in the Scrap Box at Jack's. Can you help to identify?

I was over at Jack's trying to find some moulds and I came across these figures in a box of scarp figures.  I have no idea who made them and Jack can't recall.  Does anyone recognise these?

All the figures are 20mm

Figure 1

French WW1 or Polish WW2?  

Same figure just one has lost his bayonet.

Figure 2 
WW2 Germans

Figure 3
WW2 German Paratrooper - 
This figure was designed without a base.  I used a bit of 'blu-tac' jjust to keep him upright for the pictures

Figure 4

WW1 German or Franco Prussian War Prussian?.  
The figure is very slight.  On first impressions it looks less than 20mm simply because it is thin.  However, when you stand it next to one of the figures shown above it is roughly the same height.

Any help would be appreciated.
