Are you trying to rebuild an existing panel, or build a new one just like the one you show in photos? The control panel wiring shown in your photos appears to be in good condition, so why is there a need to rebuild it?
Do you have a wiring diagram, or a ladder-logic diagram, of the existing control panel to work from? Do you have a wire list identifying each wire on the control panel by insulation color and wire gauge and where each end of each wire is connected? Every wire in the control panel should have its own unique number, ideally identified by a marker wrapped around the wire, but some of your wires are bundled in groups with the group identified by a number. Even this is not consistent because in your photo 4.jpg several bundles have the same number.
You need to build a wire list before you even think about rebuilding this panel. You do this by first disconnecting the end of ONE wire, then probing around with a continuity tester to find the other end. When you think you have found the other end, disconnect that end too and verify there is continuity between the two ends of the SAME wire. If there is no continuity, you have a "sneak" path and must continue probing to find the other end of the wire. Number each wire you find in numerical sequence and identify the location each end is connected to.
From the size and number of wires in your photos, it will take several weeks to build a wire list. It is very important that you perform that task with perfect accuracy. It is not strictly necessary that each wire be physically identified with its wire number, although this does make troubleshooting much easier. What is absolutely necessary is that you uniquely identify each wire and the terminal where each end of that wire is connected.
Since you do not seem to recognize common barrier terminal strips, or industrial control relays, why do you think you are in any way qualified to rebuild (or build) this panel? What are the consequences of failure to complete your mission correctly?
It's good that you recognize the need for help and have sought advice here, but I think you may need some "hands on" guidance at your location too. Panel building is a rather specialized trade and often boring, monotonous work requiring extreme attention to detail. Most of the time, the wiring harness is pre-built on a nail-board and then removed from the nail-board after the wires are laced up or tie-wrapped. When done correctly, this practice virtually eliminates wiring errors, especially when individual wires are color-coded AND numbered. You should probably contact a machine builder in your area for a quote on rebuilding your panel. Find out what they need to issue a firm-fixed-price quotation and then gather that information. At the very least the information you gather will prepare you to make your own panel, whether you accept the machine builder's quote or not.
Good luck,
