Can I sort each of these group associated random points SEPARATELY for each point ?

Can I sort these group of assigned point seperatly, which means I want to know exactly the group of RED points (as vectors it is not necessary to plot them) that assigned to blue Pentagon seperately. Thanks in advance

the line that I want to change it

plot([PosUE(inrange,1) PosBSs_x(BSidx(inrange))]', ...
    [PosUE(inrange,2) PosBSs_y(BSidx(inrange))]','b');

whole code

ro=1000; % radius of the layout circle 
NumBSs=6;  % Number of Base stations
NumUEs=50;   % Number of users
center=[0 0]; % center of the circle
maxrange = 250; % max range for base stations (stars)

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;
[minD BSidx] = min(D,[],2);
inrange = minD <= maxrange^2;
numinrange = nnz(inrange);
