Hello,

01. You can read our detailed documentation about image alignment and content in the following link:
https://xtemos.com/docs/woodmart/faq-guides/image-size-content-alignment-product-grid/

02. Sorry there is no option in theme setting available for that but alternatively you can add a brand menu using custom links in that place.
Here looks like:

03. I saw the screenshot you attached. Sorry, but there is no option in Theme Settings to remove the links from the brand slider items. But you can add a simple image slide to achieve that.

4. Add this code to the Theme Settings > Custom CSS > Global:

.woocommerce-breadcrumb a,.yoast-breadcrumb a {
    background-color: red !important;
}

Best Regards.
