function YourGUI_popup1_callback(hObject, event, handles)
  choice = get(hObject, 'Value');
    popups = [handles.popup2, handles.popup3, handles.popup4];
    set(popups, 'Visible', 'off');
    set(popups(choice), 'Visible', 'on');

Why wait until the user interacts with popup2 to set the items in it? That's your problem. Set the items in popup2 immediately as soon as you know them in the popup1 callback. You can set the values/properties of any other controls in any callback since you have the handles of everything. So in popupmenu1_Callback(), after you determine "list", do this

handles.popupmenu1.String = list; % Preferred/recommended way

Or, if you have an antique version of MATLAB, use set():

set(handles.popupmenu1, 'String', list);  % Ancient way

Obviously you'd then also take out any code for setting the items in the popupmenu2 callback.

vedesh - in the pushbutton callback, you would use the handles structure to get the selections from the two dropdown menus. Your code could look something like the following

function pushbutton1_Callback(hObject, eventdata, handles) 
% get the selection from the first drop down menu
popup1List = get(handles.popup1,'String'); % get the list of items of popup1
popup1Index = get(handles.popup1,'Value'); % get the index of the selected item of popup1
popup1Value = popup1List{idx};             % get the value of the selected item of popup1
% get the selection from the second drop down menu
popup2List = get(handles.popup2,'String'); % get the list of items of popup2
popup2Index = get(handles.popup2,'Value'); % get the index of the selected item of popup2
popup2Value = popup2List{idx};             % get the value of the selected item of popup2
% note that popup1Value and popup2Value are strings so you may need to convert to numbers is
% applicable
% do whatever work you need to and draw line on axes
