Can I combine two markers together, and make them overlap?

I have a number of points represented by a circle marker. These markers overlap each other, but one is always layered "above it"\"in front of it" so that one circle is seen completely while the second is hidden behind it. Can it be possible to combine them, so that the overlap is constant between both markers?
Thank you in advance!
First image shows my result. Second shows wanted result.

You can set different sizes for the markers so that they don't overlap completely.
plot(x, y, 'bo', 'MarkerSize', 15); % Use blue circles of size 15
plot(x, y, 'ro', 'MarkerSize', 25); % Use red circles of size 25.

I see the images that you attached recently, which help make the situation clearer.
However, my answer is still No: as long as you are using Markers then the combining rules are out of your control, and might depend in part on the graphics driver.
The solution is: "Don't use Markers for this purpose".
Have you looked at https://www.mathworks.com/help/bioinfo/ref/molviewer.html and https://www.mathworks.com/matlabcentral/answers/196899-how-to-draw-smooth-balls-spheres-and-sticks-cylinders-around-my-xyz-points and https://www.mathworks.com/matlabcentral/fileexchange/55231-molecule3d ?

No, it is not possible.
Consider rendering into an image and using the computer vision insertMarker routine. This will not be exactly the same: in particular regular markers stay the same size as you zoom in but markers rendered into an image would scale as you zoom in.
