Is there a way to assign the RED points which are located within the STARS range (assume STARS have range (as circle) is 100m raduis), while the RED points that are located out of the STAR range let them associated to the ''BLACK + which is range the outer circle that has raduis 1000m'' ?
ro=1000; % radius of the layout circle
NumBSs=10; % Number of Base stations
NumUEs=50; %Number of users
center=[0 0]; % center of the circle
theta_BSs=2*pi*(rand(NumPoints,1)); % distributed random number of Base stations
g = 0.5 * ro + 0.5 * ro * rand(NumBSs,1);
PosBSs_x=center(1)+g.*cos(theta_BSs);
PosBSs_y=center(2)+g.*sin(theta_BSs);
theta1 = rand(NumUEs, 1) * 2*pi; % distributed random number of Users
r1 = ro * sqrt(rand(NumUEs, 1));
PosUE = [r1 .* cos(theta1(:)) + center(1),r1 .* sin(theta1(:)) + center(2)];
% Initial plot objects
hfig = figure('Color', 'w');
hax=axes('parent',hfig);
% Plot of deploying points
hdots=plot(PosBSs_x(:,1),PosBSs_y(:,1),'bp',PosUE(:,1),PosUE(:,2),'r.','MarkerSize', 12);
grid on
hold(hax, 'on')
axis(hax, 'equal')
% Plot the layout as circles
t = linspace(0, 2*pi);
plot(ro * cos(t) + center(1),ro * sin(t) + center(2))

Here's a start. I used different colors for clarity, but you can change that to whatever you want.
ro=1000; % radius of the layout circle
NumBSs=2; % Number of Base stations
NumUEs=50; %Number of users
center=[0 0]; % center of the circle
maxrange = 1000;
theta_BSs=2*pi*(rand(NumBSs,1)); % distributed random number of Base stations
g = 0.5 * ro + 0.5 * ro * rand(NumBSs,1);
PosBSs_x=center(1)+g.*cos(theta_BSs);
PosBSs_y=center(2)+g.*sin(theta_BSs);
theta1 = rand(NumUEs, 1) * 2*pi; % distributed random number of Users
r1 = ro * sqrt(rand(NumUEs, 1));
PosUE = [r1 .* cos(theta1(:)) + center(1),r1 .* sin(theta1(:)) + center(2)];
% find which UE points are within range of a BS
D = (PosUE(:,1)-PosBSs_x.').^2 + (PosUE(:,2)-PosBSs_y.').^2;
inrange = any(D <= maxrange^2,2);
numinrange = nnz(inrange);
% Initial plot objects
hfig = figure(2);
hax=axes('parent',hfig);
% Plot of deploying points
hdots(1) = plot(PosBSs_x,PosBSs_y,'bp','MarkerSize', 12); hold on
if numinrange > 0
hdots(2) = plot(PosUE(inrange,1),PosUE(inrange,2),'g.','MarkerSize', 12);
end
if numinrange < NumUEs
hdots(3) = plot(PosUE(~inrange,1),PosUE(~inrange,2),'r.','MarkerSize', 12);
end
% Plot the layout as circles
t = linspace(0, 2*pi);
plot(ro * cos(t) + center(1),ro * sin(t) + center(2))
grid on
hold(hax, 'on')
axis(hax, 'equal')

You should be able to just do a logical combination of the two conditions:
inrange = (mindistD >= maxrange^2) & (mindistD<= maxrangeD2^2);
