for b=0:pi/80:pi/8;
    pause(.5)
    B=A+[10*cos((-pi/8)+b), 10*sin((-pi/8)+b)];
    circle2=viscircles(B,5,'LineWidth',2,'Color','green');
end
%Circle C
for c=0:pi/40:pi/4;
    pause(.5)
    C=B+[10*cos(-(pi/4)+c), 10*sin(-(pi/4)+c)];
    circle3=viscircles(C,5,'LineWidth',2,'Color','blue');

To get them to run at the same time, you have to run them on separtae CPU cores. To do that you need to use parfor (instead of for), which is in the Parallel Processing Toolbox.
