Perhaps you have good reason for creating the faceted surfaces with holes? You could also split the original surface using Isotrim (SubSrf) like this:
For what it’s worth (not much difference), I added an Align Plane component just before Polygon using the ‘V’ direction instead of the default ‘U’ orientation.
By the way, the same holes can be cut into the original surface without splitting it into fragments.
P.S. Here’s one way to do that:
Or using the corners of the Isotrim surface fragments to make the Srf4Pt faceted fragments:
I noticed that the referenced surface is semi-faceted in the ‘U’ direction (crosswise) with only four facets, not five, so I changed the ‘U Count’ slider from 5 to 4 to match that.
