How to add two other curves to the final plot ?

Hello ! So I actually have two questions. The first one obviously is that I want to run the following script for three sets of Y values, that share the same X values, and I would like the scriopt to plot the 3 curves into one single plot. I only have basic knowledge of Matlab and don't want to mess up this script. Second, I would like the output text to be written in a column instead of a line, and return the same parameters for the 2 supplementary curves that I want to add. Does anyone have an idea to accomplish all of this ? Thanks !
