Importing figure from another script for a G.U.I

I have several figure plots named

figure(1), figure(2)

etc already defined in a script and I now want to place all of these figures together by creating G.U.I with them included

When I go to file>new>G.U.

I it creates a blank G.U.I in a separate script. I want to concatenate everything together so I can work on my G.U.I design within the same script or work with the blank G.U.I script such that it calls my figure names/variables etc from the main script i've been working on already.

Is it possible to do it all within the same script? Or how can I call my figure plots in the blank G.U.I script? Here is an example of the figures i'd like in my single G.U.I window:
