Hello,
2) Sorry but there is no option in Theme Settings available for that. It requires customizations and this is beyond our limitations and support policy.
1) For the permalink you can enable the shop base to add a shop in the breadcrumbs from Settings >> Permalinks >> Product permalinks >> Set to shop base. Otherwise it requires customizations

3) Related Products is a section that pulls products from your store that share the same tags or categories as the current product.
4) Please try adding the following Custom CSS in the Global Custom CSS area under Theme Settings >> Custom CSS.
form.woocommerce-ordering {
display: none;
}
5) You can try changing the name of the page you set as the woocommerce SHOP.
Best Regards
.
