Yet again, you have found some interesting weights, even if some are not the best quality.
Could you please give the sizes of these weights?
I agree with Frank about number 1. The canes are all known from that period (and perhaps even earlier?).
Number 2 looks like a mid-European shape to me, but I have never seen one with that type of "flower" before. It's another one with good complex canes but which have suffered in the making of the weight.
Numbers 3 & 4 ... seem to me to be by the same maker, although one has a very rough-ground base (like some older German weights?) and the other has an impressed mark (like English Channel Islands!?!).
For number 3, when the picture was being shown for the first time, I saw the outer canes and said to myself, "That's another Ysart Brothers weight". When I saw the next row of canes, I still thought it was Ysart Brothers, although I don't think I have seen that exact cane beore. When next set of canes came into view I said, "Oh, no, those look like Murano canes!".
Although the outer canes do have a similar look to some Ysart Brothers ones - particularly with the red, white and green colours in that sort of patterning, the green seems too bright. I don't think I have seen the central canes before but the green seems to be the same as in the outer canes. And those inner row canes do look so much like the Italian flag - blocks of Green, White, Red.
It would be good to find out who used the impressed mark on the base of number 3. So far, I cannot locate it. Can you get a photo (or a drawing) of it that shows the detail a bit more clearly?
Number 4 ... is clearly of poor standard and again, at first, I thought the canes types and colouring could be Scottish (Ysart Brothers). Like number 3, I now think these are probably Murano canes. But ... the base finish is more like central European (German?) items!
Number 5 ... Another with a confusion of identity. The base is yet again more like old German (just my opinion), but the canes look more like Murano (although I don't actually recognise them) and could, I suppose, be old Bohemian or Czech. Or ...
These last four weights are fascinating, whatever they are.
