Here It's quite obvious that you are trying to insert same articles again which already exist in your database.
And I've already stated in my previous messages, what you need to do if you are intending to update existing articles and insert the new one. Here It is again:
"If you are intending to update the Articles, then there is an option in Profile settings to choose Insert or Update operation, choose update over there and If you choose update then you must have primary key field in your data file i.e. ID in case of Joomla articles."
So just make sure you have chosen "Update" in "Operation" parameter, "Include" in "ID" parameter and have the "ID" column exported in your CSV file.
