How can I can I draw multiple circles with figure that have character into them

Hello I made a Matlab project where I plotted two circles that represented electrical charges.

And i used this code

figure();
h=rectangle('Position',[xCn-a/2,yCn-a/2,a,a],'curvature',[1 1]);
set(h,'Facecolor',[0 0 0],'Edgecolor',[0 0 0]);
text(0.43,0.05,'-','Color','white','FontSize',30);
h=rectangle('Position',[xCp-a/2,yCp-a/2,a,a],'curvature',[1 1]);
set(h,'Facecolor',[1 0 0],'Edgecolor',[1 0 0]);
text(-0.6,0,'+','Color','white','FontSize',30);

How can I Draw 5 circles for each charge with their sign so it looks like this? I only need help for drwaing the circles ignore the blue arrows

Thanks for your answers

Try viscircles() in the Image Processing Toolbox.
