How to put legend in subplot automaticaly using for end?

Can anyone help me how to put legend in left and right figure as shown below? Since this figure generate by looping (for-end), I wonder if legend can also generate using looping format

For legend location as per image above you will need lcoation as

northeast

and

northwest

or you can use text function to place annotation on subplots like below.

% Number of subplots
nPlots = 3;

% Number of lines per plot
nLines = 1;

figure;

for i = 1:nPlots
    subplot(3, 3, i);
    
    % Generate random data and plot
    y = rand(1, 100);
    plot(y);
    hold on;
    
    % Determine axes limits for positioning text
    xlims = xlim;
    ylims = ylim;

    % Position text at top-right corner
    xPosRight = xlims(2) - 0.05*(xlims(2) - xlims(1));  % 5% from the right edge
    yPos = ylims(2) - 0.05*(ylims(2) - ylims(1));       % 5% from the top edge
    text(xPosRight, yPos, num2str(randi([1, 99])), 'HorizontalAlignment', 'right');
    
    % Position text at top-left corner
    xPosLeft = xlims(1) + 0.05*(xlims(2) - xlims(1));   % 5% from the left edge
    text(xPosLeft, yPos, num2str(randi([1, 99])), 'HorizontalAlignment', 'left');
    
    hold off;
end
