Answer 1

It is due to you have not removed entries for the product URL Keys from url_rewrite table. Moreover it is not a proper way to delete a product because by doing this you are just removing entries from main product table where as all other tables will have data related to those products and it will duplicate data in related tables. Apart from that your table size also will increase due to dumping of data which is unused as you delete entries from main table.
