That's always difficult; it does become significantly harder to give good criticism when you feel that a work is very strong to begin with. Like TurkishMonkey said, it's important to say why you thought their stories are good--the more specific you can be, the better.
Other than that, since these are stories you are critiquing, not essays, even your basic emotive reactions can be helpful. You can comment on which characters you liked or disliked, which scenes or lines were or were not convincing, and so on.
Don't feel too bad if you can't come up with anything negative, though--positive comments can be helpful, too, as long as you are telling the writer why its good aspects work, not just that you like the story.
