Rectangle Loft around Curve Issue

Hi there!

I am trying to make a rectangle face directly towards the area (central points) of my tower. This is to make an interlocking structure on the facade (like a waffle structure but arranged radially) which I can then laser cut so it must be planar. Here is an example of one that works:

I am currently stuck because only two of the fins work (the left and right in top view) and want to figure out how to make the other curves have a rectangle facing the centre points. The two work because the rectangle was made in the default xy plane but I am trying to create new xy planes towards the mid point and it is not working.

The curves are all different

Does anyone have any suggestions?
