How to make this figure more simple with 'for'

I made some figure. But I want to make more simple this. But it's hard for me to make that.

could you help me?

And other problem is when I run this.

7Hz and 6Hz are plotted in one figure.

But 7Hz and 6Hz are isolated.

I appreciate you if you help me...

What does this mean:

7Hz and 6Hz are plotted in one figure. But 7Hz and 6Hz are isolated.

? If you provide some input, we could run your code. Is "v_t" a vector or a function?

That is, I want to devide into two plot not one plot that has 7Hz and 6Hz.

Remember that the readers can read the question only, but not your mind. I cannot guess, what you want to divide into what. The details "6Hz" and "7Hz" occur in the code only as a comment "% everything_6Hz". Maybe all you want is to replace the subplot calls to:

subplot(2,2,1);  % Instead of: subplot(1,2,1)

to move the last diagrams to specific axes.

By the way, your code would be much nicer, if you use a loop instead of hiding indices in the names of the variables:

LineStyleList = {'-', '--', '.-', ':', 'none'};
NameList = {'0.0 V', '0.5 V', '1.0 V', '1.5 V', '2.0 V'};

aaList = [0, 5];
for iaa = 1:numel(aa)
    aa    = aaList(iaa);
    sub   = (iaa - 1) * 2 + 1;
    AxesH = [subplot(2, 2, sub,     ...
        'NextPlot', 'add', 'Box', 'on'),  % Implicit: hold on, box on
        subplot(2, 2, sub + 1, ...
        'NextPlot', 'add', 'Box', 'on')];
    for k = 1:5
       v  = v_t(1:1250, k + aa) * 1000;
       f  = f_t(1 + delay(k + aa):1250+delay(k + aa), k + aa);
       dk = dk_t(1 + delay(k + aa):1250+delay(k + aa), k + aa) * 1000;
       plot(AxesH(1), v,  f, 'LineStyle', LineStyleList{k});
       plot(AxesH(2), dk, f, 'LineStyle', LineStyleList{k});
    end

    xlabel(AxesH, 'Velocity (mm/s)');
    ylabel(AxesH, 'Force (N)')
    legend(AxesH, NameList, 'FontSize', 8);
end

So if you start with this, what do you want to modify?
