Hello, @IP,
1. You can change the style from XStore >> Theme Settings >> WooCommerce >> Shop >> Product Styles as per your requirements.
2. You have to move that button using the Custom CSS in that style, please share the screenshot that where you want that button to appear in that style so that I will try to create the CSS for you, else, you can simply change the style of the product by following the 1st point.
3. For that Quick View button color change, you have to go to XStore >> Theme Settings >> Theme Custom CSS >> Global CSS and change the color in that code: https://ibb.co/WVKNBjq as per your requirements.
