No, that's completely fine as long as you delve deeply into all of your texts - don't try and do 2 texts if you're only going to allocate like 5 minutes of analysis into one of them.
It might also be a good idea to look at the question (and if it says 1 related text) choose whichever text is better suited to the question.
Edit** just to clarify, this is if the question says something along the lines of: support with at least one related text.
