I prefer to store and share data with the function setappdata and getappdata. This is, in my opinion, more clear and better structured.

If you used GUIDE, you need to use guidata() on the figure number for GUI2 in order to get GUI2's handle structure in GUI1. Then you can change things in the normal way. For example,
handles2 = guidata(GUI2_figure);
set(handles2.Num1, 'Value', get(handles.Num1, 'Value'))

When I put the aboves commands in pushbutton1 of GUI1, error:【Erroring using get; Convertion to duoble from cell is impossible.】
So where to put above command? Thank you very much!
