is it possible to print comments with Pages 5.0

No. Use Pages 09, which should still be one your computer. And tell Apple how you feel about the embarrassing disaster that is Pages 5.0.1 at

At present, no. The solution (if you can call it that) is to use Pages09 to produce the document or import the document you created in Pages 5.0 into Pages09 for printing.

If you had Pages09 and upgraded to 5.0, Pages09 will still be in your Applications folder.
