Hello,
If you want to add description and additional info in your product then edit your product and add your’s description in WP-Bakery block.
Screenshot for clarification: https://jmp.sh/FjMC2R3
In general the additional information tab only shown when you add attributes to the products. If you want to add the Additional information tab you have to add all those attributes from the product as in the screenshot: https://jmp.sh/2pFIr97

To add SKU/category/share after the product tabs. Then go to theme settings >> Product Page >> SHOW / HIDE ELEMENTS >> Show product meta. You need to choose “After Tabs” option.
In order to display “You may also like..” you need to enter a product editing mode and add products into Upsells of Linked product tabs as shown: http://prntscr.com/j5tv88
You will find more information here: https://docs.woocommerce.com/document/related-products-up-sells-and-cross-sells/
To display the related products section you need to enable the “Show related products” option from Theme Settings >> Product Page >> SHOW / HIDE ELEMENTS.
Then you have to select a category from the product edit page as in the screenshot: https://jmp.sh/yqABzGC
For example, if you have three products and all of them are of the same category then in the related products section of all those three products the other remaining 2 products will be shown.
No, there is no such option to show you may also like section in the right sidebar.
Best Regards.
