The DisplayName name-value pair will use that information for the legend entry for each plotted pont. If you want the station number displayed next to each symbol, usee the text function.
The problem with your original code is that the scatter function syntax is different from other plot-type functions. Give it the command syntax it is expecting and the colors plot correctly.
Try this —
clear all;
clc;
A=dir('*.mat');
numprof = length(A);
couleur = jet(numprof); %prefered colormap is jet
for nn=1:length(A)
filename = A(nn).name;
B = load(filename);
xp = B.T.xpos(1);
yp = B.T.ypos(1);
sta = B.T.station(1);
% scatter(xp,yp,50,"square",'filled','color',couleur(nn,:), 'DisplayName', string(sta)); % it seems not following the jet colormap setting
scatter(xp,yp,50,couleur(nn,:),"square",'filled', 'DisplayName', string(sta)); % it seems not following the jet colormap setting
hold on;
end
hlgd = legend('Location','best');
title(hlgd, 'Station Number')
axis('padded')
% return
clearvars
mats = dir('*.mat');
for k = 1:numel(mats)
filename{k,:} = mats(k).name;;
LD = load(filename{k});
S{k} = LD.T;
end
filename{:}
% format long
% S{:}
cm = jet(numel(S));
figure
hold on
for k = 1:numel(S)
scatter(S{k}.xpos(1), S{k}.ypos(1), 200, cm(k,:), 'filled', 's')
text(S{k}.xpos(1), S{k}.ypos(1), sprintf(' Station %d',S{k}.station(1)), 'Horiz','left', 'Vert','middle')
end
hold off
grid
axis('padded')
xlabel('xpos')
ylabel('ypos')
As with the previous problem, you can use one loop for this. I used two loops because I wanted to see what the .mat fiiles contained, before I proceeded with the plot.

Minor tweaks.
