Vlad - assuming that you are using GUIDE to create your GUI, suppose your five popup menus are named popupmenu1, popupmenu2,..., popupmenu5. If we assume that only numeric data has populated each of your popup menus, then the callback for your push button would look something like

 function pushbutton1_Callback(hObject, eventdata, handles)
 % get the list of items in the first popup menu
 menu1List = get(handles.popupmenu1,'String');
 % get the selected item in the first popup menu and convert to a number
 menu1Item = str2num(menu1List{get(handles.popupmenu1,'Value')});

You would then just repeat the above code for the remaining four popup menus and do whatever operation you need against them.

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
