With you standard lens kit the these macro rings just mean that you can get focused further away from your subject in macro mode.
If you want to take a macro pic of a fly the chances are as you get closer to it it will fly away, so these rings allow you to use macro mode on your camera but instead of having to be say 5 cm away they allow you to get the same magnification but at a greater distance from your subject say eg 20 cm without spooking it.
the 1 and 10x rings probably wont be much use but the 4 should be about right.
you will have a very very small field of focus in macro mode so you may want to get into using focus stacking.
