I have a popup menu.

And the popup menu has three choices.

I wish to load amount of money such as $5,$6,$8 for clicking the choices in popup menu,set it in the GUI's uitable and store it for calculations. How can I do that? Please help.

Use a set of conditional statements (either if, elseif and else, or switch and case) in the callback to the popup menu.

If I choose from the popup menu, the previous data is cleared. What code do I need to use to ensure that the previous data does not get cleared?

Your code has function popupmenu1_Callback that contains
contents = cellstr(get(hObject,'String'))
pop=contents{get(hObject,'Value')}
for i=1:4
sel_sts{i,1}='i';
end
if(strcmp(pop,'Pop-up Menu'))
set(handles.uitable1,'data',sel_sts);
elseif(strcmp(pop,'book'))
set(handles.uitable1,'data',sel_sts);
elseif(strcmp(pop,'pen'))
set(handles.uitable1,'data',sel_sts);
end
Each of those set() is replacing the existing data in the uitable with the new cell array sel_sts .
Note that you are doing the same set() each time, so your code could be compressed to
if ismember(pop, {'Pop-up Menu', 'book', 'pen'})
set(handles.uitable1, 'data', sel_sts);
end
I wonder, by the way, if you really want to set those entries to the literal character 'i' in the for loop, or if you want the value of i?
for i = 1 : 4
sel_sts{i,1} = i;
end
