MATLAB: How can you use a GUI pop up menu to display file name in a folder

You could use a pop up menu populated with names of files that you want the user to choose or you could use a push button whose callback opens file selection dialog (see 'uiopen') and the user chooses a text file from here. I think you have figured out how to read the text file (see 'fileread' and 'regexp') and plot it. You could put all this in a script or function file and place it in the callback function for the UI object.

MATLAB: How to create a list with all variables to let user choose those he wants for

Try to access variable names dynamically will be buggy any slow, and is not recommended. No matter how much beginners love inventing the idea, trying to access variables names like this will always make code be slow and impossible to debug:

A much simpler, faster, and easier way to code this would be to put all of the data into one structure. Then the task is trivial:

% Define a structure:
S.X = 'anna';
S.Y = 'bob';
S.Z = 'cath';
% Let the user pick some of the fields:
C = fieldnames(S);
idx = listdlg('PromptString','Select variables',...
              'SelectionMode','multiple',...
              'ListString',C);
% Show the values of the fields that the user picked:
for k = 1:numel(idx)
    S.(C{idx(k)})
end
