"How do I cange the Xticklabels of a plot using figure handles?"
Get the axis handle from the figure handle.
ax = gca(figureHandle);
Get the XAxis handle from the axis handle and set the FontSize of the x-axis only.
ax.XAxis.FontSize = 16;
or set the fontsize of the entire axis (x & y)
ax.FontSize = 14;
Set the XTick and XTick labels
ax.XTick = 1:4;
ax.XTickLabel = {'A' 'B' 'C' 'D'};

There are xticklabels() and yticklabels() functions built-in. From the help:
xticklabels(labels) sets the x-axis tick labels for the current axes. Specify labels as a string array or a cell array of character vectors; for example, {'January','February','March'}. If you specify the labels, then the x-axis tick values and tick labels no longer update automatically based on changes to the axes.
Also, see my little demo that shows you how to change a bunch of things independently:
% Create sample data.
X = 1 : 20;
Y = rand(1, 20);
plot(X, Y, 'gs-', 'LineWidth', 2, 'MarkerSize', 10);
grid on;
title('Y vs. X', 'FontSize', 12);
% Make labels for the two axes.
xlabel('X Axis');
ylabel('Y axis');
% Get handle to current axes.
ax = gca
% This sets background color to black.
ax.Color = 'k'
ax.YColor = 'r';
% Make the x axis dark green.
darkGreen = [0, 0.6, 0];
ax.XColor = darkGreen;
% Make the grid color yellow.
ax.GridColor = 'y';
ax.GridAlpha = 0.9; % Set's transparency of the grid.
% Set x and y font sizes.
ax.XAxis.FontSize = 15;
ax.YAxis.FontSize = 24;
% The below would set everything: title, x axis, y axis, and tick mark label font sizes.
% ax.FontSize = 34;
% Bold all labels.
ax.FontWeight = 'bold';
hold off

You could turn the text labels off and then make your own tick labels with the text() function and place it wherever you want.
