How do I change the font size of the labels in my legend? For example, how do I make the font size of the ‘One’, ‘Two’, ‘Three’, ‘Four’ labels bigger in my plot?

Starting in R2022a, you can use the fontsize function to change the font size within a figure or for a particular object, such as a legend. You can set the font size to a specific number, or you can incrementally increase/decrease the size of all the text for the object while maintaining relative size differences.   
For example, this code creates a plot and a legend and sets the legend's font size to 14 points. 
lgd = legend('One','Two','Three','Four');
This code decreases the font size by a factor of 0.9. 
R2022a also includes the fontname function, which enables you to change all the fonts within the figure or for a particular object in the figure. 
For previous releases:
You can change the font size for a MATLAB legend by setting the 'FontSize' property of the Legend object.
For example, plot four lines. Create a legend and assign the Legend object to the variable 'lgd'. Then, use dot notation to access the 'FontSize' property and set the value to 14 points.
lgd = legend('One','Two','Three','Four');
lgd.FontSize = 14;
Alternatively, you can specify the 'FontSize' property using a name-value pair argument in the 'legend' command. When including name-value pair arguments, include the legend labels in a cell array. For example:

Here you go :
h = legend('x','y','z');
