Hi,
The red messages indicate that you had created characteristics on the old website and used them in your products but you didn't create the characteristics in the new website before the import. And thus, the import complains that it has data for the products that it can't add because it doesn't know what to do with these extra columns.
The blue messages indicate that you have some rows in the CSV without product data, and that's normal as these are the category tree rows, so you can ignore them.
The last message indicate that some rows couldn't be imported. That's probably the variants of the products (since the characteristics are missing).
So you should recreate the characteristics with the values similar to how you have them in the old website and redo the import and it should work fine.
Alternatively, you can export the hikashop_characteristic table and import it on your new website via PHPMyadmin. It will automatically add all the characteristics and their values so you can just run the import after that.
