"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'};
