It is probably best to not connect the relay power supply to the breadboard. Use that to power the relay boards only.
The 5V power from the Pi is enough to power the shift registers.
you asked:
"Am I correct to assume that the insertion points are connected by rows in groups of 5. For example 1A, 1B, 1C, 1D, 1E are connected within the BREADBOARD."
Yes. that is correct
