I'm new to matlab and am having showing all 16 graphs only a few to be showing up. The current code is:
clear
clc
N = 256;
n = 0:N-1;
x0000 = [ones(16,1); zeros(240,1)];
x0000 = x0000/norm(x0000);
x0001 = [zeros(16,1); ones(16,1); zeros(224,1)];
norm(x0001);
x0001 = x0001/norm(x0001);
x0010 = [zeros(32,1); ones(16,1); zeros(208,1)];
norm(x0010);
x0010 = x0010/norm(x0010);

If you do not hide an index in the name of the variable as in "x0000", but use an array instead, the code could be simplified massively using loops.
The notation "subplot(928)" is outdated for over 25 years now. Prefer the modern subplot(9, 2, 8).
You post some code. What is your question? What do you want to "combine" and how?

You have to define all your subplots in the [9 2] grid - the code you present show the first 9 graphs in a [9 1] grid and the last 7 in a [9 2] grid.
That would be that you change the code to
subplot(9,2,1);
stem(n,x0000, 'b','Marker','none','LineWidth',1)
title('Signal x0000 - Transmit to send a digital 0000','fontSize',18)
subplot(9,2,2);
stem(n,x0001, 'r','Marker','none','LineWidth',1)
title('Signal x0001 - Transmit to send a digital 0001','fontSize',18)
% Many lines to follow until
subplot(9,2,10);
stem(n,x1001, 'r','Marker','none','LineWidth',1)
title('Signal x11 - Transmit to send a digital 1001','fontSize',18)
subplot(9,2,11);
stem(n,x1010, 'r','Marker','none','LineWidth',1)
title('Signal x11 - Transmit to send a digital 1010','fontSize',18)
% Finishing with
subplot(9,2,16);
stem(n,x1111, 'r','Marker','none','LineWidth',1)
title('Signal x11 - Transmit to send a digital 1111','fontSize',18)
noisefactor = 0.2
TX = randi([1 16]);
y=signals(:,TX) + noisefactor*randn(size(x0000));
y=y./norm(y); % normalize y
subplot(9,2,17)
stem(L,L,'k','Marker','none','LineWidth',1)
title('Received signal - Which Symbol is it?','fontSize',18)
Which for your full code could be something like this
