Pic No3 is a boot/shoemaker shop or a cobbler's shop, it has the traditional sign of the boot above the window, window is full of footwear
Pic No1 maybe brickmakers or brick kiln workers, note the clogs, they were used in industry generally where the workers had to stand on hot furnace floors to fettle or moulding beds when the moulds were broken open, One boy is holding a brick and the other boy a chimney pot or a piece of drainpipe.
