How to break down the curve into small rectangles

See this?  It derives a "best fit grid size", though it ended up being a suggested new perimeter curve because dimensions had no common divisor:

square grid inside a non regular shape

It works on your shapes too, one at a time.  Your "columns" are internalized in this GH code, with 'Join' to connect the separate lines into perimeter curves.

This is version 'e' from the other thread, adapted to use your curves (again, internalized here).  Grafting them makes this code work with all columns at once.  You manually adjust the 'grid size' slider.  Will need a little work to give you what you want but it's a start, eh?

If it is just for 5 curves you could make it by hand.
If you need automatic algorithm it is doable with a custom program
Close your curves
Take point 0
Point 1
Point 2
If point 3 = point 0 end
Else make a rectangle with point 0 1 2 substract from the first closed polyline and continue
There are surely other alternatives using surfaces. David Rutten did a program tu transform a trimmed surfaces in I trimmed surfaces
