1. You can hide it adding the following code snippet to the Custom CSS section for mobile devices in Theme Settings

.footer-column-1 {
	display: none;
}

2. You can hide some particular columns on mobile devices with Visual Composer while editing them.

3. You can increase logo width in Theme settings -> Heade -> Logo.

4. Sorry, but there is no such option in WooCommerce.
