Do you have the data available in variables? If not then do you have .fig files of the plots that the data can be extracted from? Or do you just have images showing plots of the data?

You can use hold to hold the current graph on the plot and keep plotting on the same axis unless you remove the hold.

 plot(strain,tstress)
 hold on
 plot(tstress,fstress)
 ...
 hold on

then you might also want to use legend to identify each line.
