subplot(1,6,1);
plot(u(t-3));
grid on
ylabel('u(t-3)')
subplot(1,6,2);
plot(u(t+1));
grid on
ylabel('u(t+1)');
subplot(1,6,3);
plot(z(-t-3));
grid on
ylabel('z(-t-3)');
and so on.

t and n should be arrays defining your x axis elements, like
t = 3 : 1 : 100; % or whatever.
I don't know of any integer n that will allow you to get integer index numbers for both -2*n-1 and 3*n+2, so I don't see how u can be a list of values of u.

... that would allow you to get positive index numbers ...
But perhaps u and z are functions instead of arrays.
