Can Students reply to Peer Answers?

Is there a way we can have students provide feedback to each other? Maybe ask follow-up questions or make comments. I’m envisioning something where student responses are shared (even just a few are okay) and students can comment. The original student will see the feedback provided then for their initial post. This would support an AVID tutorial style of lesson.

Short answer is no.
If you had some canned response options you may be able to build something fancy using “aggregate” but there is nothing like this readily available.
