I need to scale out elasticsearch. Can you recommend right amount of data nodes? Thank you in advance.

That depends entirely on your use case and your data volumes, so without a lot more information I do not see how anyone can even try to answer that.

No, that is not nearly enough. We do not know anything about your use-case, set-up, hardware or the problems you are facing that led to the conclusion you need more data nodes.

I would recommend you review the following resources:
