Looping through Axes on figure created using subplot

Hello, I have a figure with 5 subplots on.
hf1=figure('position',pos,'Name','4LineScan'); % pos defined elsewhere
ax1=subplot(1,5,1); ax2=subplot(1,5,2); ax3=subplot(1,5,3);
ax4=subplot(1,5,4); ax5=subplot(1,5,5);
I then want to perform the same operation on different data and plot on one of each of the axes. Rather than have my code sequencial, Im thinking of doing it in a loop, but am trying to be able to get each axes in a loop.
I thought this might be one way
hChild = findobj(hf1, 'Type','Axes' )
h1=hChild(1)
But I want to be sure that on iteration 1 of the loop it picks out ax1, and then ax2 etc. Is there a way to do this
Thanks

As you are working with R2022b, (imo) it would be better to use tiledlayout and add plots to tiles using a for loop.

% store the axes in an array:
ax = [ ...
subplot(1,5,1) ...
subplot(1,5,2) ...
subplot(1,5,3) ...
subplot(1,5,4) ...
subplot(1,5,5) ...
];
% then it's easy to access the ii-th axes in a loop:
for ii = 1:5
% do whatever you want with ax(ii)
end

Actually I have got this to work
A=[ax1,ax2,ax3,ax4,ax5];
for i=1:5
AX=A(i)
% do what ever I want
end
It would still be nice to know how to get the actual axes name if thats possible

Joe, so "ax1", "ax2" etc, where I have deifned it earlier as ax1=subplot(1,5,1)
Joshi, it was neither.

Ran in:
@Jason: What are you going to do with ax1, ax2, ax3, ..., that you can't do with ax(1), ax(2), ax(3), ... (in my version) or A(1), A(2), A(2), ... (in your version)?
You can always construct a string that says 'ax1' or whatever
for ii = 1:5
str = "ax"+ii;
disp("Working with axes "+str);
end
Working with axes ax1 Working with axes ax2 Working with axes ax3 Working with axes ax4 Working with axes ax5
