legh = legend('Station 1','Station 2','Station 3','Station 4','Station 5','Location','southoutside');
set(legh, 'fontsize', 12)
% add legend
%Lgnd = legend('show');
%Lgnd.Position(1) = 0.4;
%Lgnd.Position(2) = 0.0;
print('DT300','-dpng','-r300');
How can I insert common legend at the outside (south) of the pic ?

I updated your question to display the result of your code. Note the warning that is produced by supplying 5 labels for 4 objects. Remove the fifth label or add a fifth object to fix that issue.

Use TiledLayout instead of subplot to create the axes. Then, after adding the legend, position it on the bottom using the tiled layout object.

Adam's answer is the elegant solution, but if you're using something older than R2020b, or if you're not using tiledlayout, you can do something like this:
p = get(gca,'position'); % store axes geometry before creating legend
legh = legend('Station 1','Station 2','Station 3','Station 4','Station 5','Location','southoutside');
set(legh, 'fontsize', 12)
set(gca,'position',p) % restore axes geometry
legh.Position(1:2) = [0.5-legh.Position(3)/2 0.02]; % roughly center legend
% shift all the axes up a bit to make room for the legend
offset = 0.05; % vertical offset per row
scale = 0.9; % amount to scale each axes vertically
gh = gcf;
h = gh.Children;
h = flipud(h(isgraphics(h,'axes')));
for ax = 1:numel(h)
h(ax).Position(2) = h(ax).Position(2) + offset*ceil(ax/2); % assumes 2 columns
h(ax).Position(4) = h(ax).Position(4) * scale;
end

If you want to make better use of the space, you can reorient the legend:
p = get(gca,'position'); % store axes geometry before creating legend
legh = legend('Station 1','Station 2','Station 3','Station 4','Station 5','Location','southoutside');
set(legh, 'fontsize', 12,'orientation','horizontal')
set(gca,'position',p) % restore axes geometry
legh.Position(1:2) = [0.5-legh.Position(3)/2 0.03]; % roughly center legend
% shift all the axes up a bit to make room for the legend
offset = 0.02; % vertical offset per row
scale = 0.95; % amount to scale each axes vertically
gh = gcf;
h = gh.Children;
h = flipud(h(isgraphics(h,'axes')));
for ax = 1:numel(h)
h(ax).Position(2) = h(ax).Position(2) + offset*ceil(ax/2);
h(ax).Position(4) = h(ax).Position(4) * scale;
end
