Thanks for contacting us! Assuming that the nylon attachments on each window are identical to the ones in the photos you uploaded, I would recommend our Series 390 in each case. For window one, I recommend our S390-28 with a 2720 option to match your old stamp. I'm afraid I cannot determine what your other windows are. You will need to check the length and stamp for each balance in each window.

I notice that window #4 doesn't have a balance, though. Can you tell me the height of the visible glass in the sash? That will tell us what length you need. Once you know the length, you can reference your sash weight on the chart we have on each Series 390 store page.
