Adding multiple legends outside for loop which is for multi variables

Hello, I used two different colourbar for two different variables.

The variables are plotted in for loop. Legends should be outside for loop.

I cannot add multiple legend outside for loop.

I know that it must not recognise leg_copy.

However, I need to put all legends outside loop. Here is the code :

hold on
    clr = jet(alphasteps);        %# 1st colormap for first variable
    clr2 = copper(alphasteps);    %# 2nd colormap for second variable
%------------------------------------------
    for l = 1:alpha steps
    ...   ... ...
    end   
%------------------------------------------
    if exist ('t_clashing', 'var') & exist ('alpha_clashing', 'var')
        t_clashing
        alpha_clashing
        t_vect = 0:dt:max(t_clashing);
        figure(5);  
            for i=1:alphasteps
                hf1 = figure('Color', 'w');
                ax1 = axes('Parent',hf1);
                hold on;
                % First set of plots
                hplot1=plot(t_vect(1:t_clashing_index(i)-20), H1L(1:t_clashing_index(i)-20, i),'Color',clr(i,:))
                hf2 = figure('visible', 'on');
                ax2 = axes('Parent',hf2,'visible','on');
                hold(ax2, 'on');
                set(hplot1,'Parent',ax2);
                set(hleg_copy,'Parent',hf2);
                hplot2=plot(t_vect(1:t_clashing_index(i)-20),H1R(1:t_clashing_index(i)-20, i),'Color',clr2(i,:))
                hold on;
                set(gcf, 'Color',[1 1 1]);
                set(hplot1, 'lineWidth', 0.8);
                set(hplot2, 'lineWidth', 0.8);
            end
            xlabel('t')
            box on
        end
    end
%------------------------------------------
    hold off
    [hleg,hobjs,hlinpatches,legtxt] ...
        = legend(hplot1,'h_1L , \alpha = -2', 'h_1L , \alpha = -1.9','h_1L , \alpha = -1.8','h_1L , \alpha = -1.7','h_1L , \alpha = -1.6','location','NorthWest');
    hleg_copy = copyobj(hleg,hf1);
    delete(hleg);
    hleg_copy = copyobj(hleg,hf1);
    delete(hleg);
    [hleg2,hobjs2,hlinpatches2,legtxt2] = ...
       legend(hplot2,'h_1R , \alpha = -2', 'h_1R , \alpha = -1.9','h_1R , \alpha = -1.8','h_1R , \alpha = -1.7','h_1R , \alpha = -1.6','location','NorthEast');
    % Create a copy of the second legend and delete the original
    % This forces similar appearance and behavior for the two legends.
    hleg_copy2 = copyobj(hleg2,hf1);
    delete(hleg2);
    set(hleg_copy,'Tag','', 'ButtonDownFcn','', 'UserData', []);
    set(hleg_copy2,'Tag','', 'ButtonDownFcn','', 'UserData', []);
    set(hplot1,'Parent',ax1);
    set(hplot2, 'Parent', ax1);
    set(hleg_copy,'Parent',hf1);
    xlabel('X-Data');
    close(hf2);

I have used that code from that answer. However, my case is different! I have to put my legend outside the loop. That is why, it does not recognise hleg_copy !
