Hi,

2. Sorry, but we don’t quite understand your question. Could you please provide some screenshots for better understanding?

4. You can disable these plugins completely in Dashboard -> Plugins.

5 & 6. Be sure that you are using simple product and it has a price and in stock to show “Add to cart button”. Quick view button is shown on your screenshot right next to read more button.

7. Try to add the following code snippet to the Custom CSS area for mobile devices in Theme Settings to fix this issue

div.banner-btn-position-hover .banner-btn-wrapper {
    display: block;
}

Regards
