Answer 1

try this one if this helps:

i have changed a little bit i used classes .plus, .minus instead of ids #plus, #minus

 $('.plus').click(function() {
    var sp = parseFloat($(this).prev('span').text());
    $(this).prev('span').text(sp + 1);
 });

 $('.minus').click(function() {
    var sp = parseFloat($(this).next('span').text());
    $(this).next('span').text(sp - 1);
 });
