The subplots are sequentially numbered from 1:N as given in the construction. To use yours just
...
for state = 5:11
subpltIdx=state-4;
subplot(2,4,subpltIdx)
...
% plot stuff goes here...
end
...
tiledlayout(2,4)
...
for state = 5:11
nexttile
...
% plot stuff goes here...
end
While neither requires it, I would strongly recommend you save the handles to the axes in a 2D array on creation -- then one can access whichever axis is needed directly to make any later changes needed.
