Hello,

1. Please try adding the following Custom CSS in the Global Custom CSS area under Theme Settings >> Custom CSS.

.single-product .price .amount {
display: none;
}

2. Sorry but there is no option in Theme Settings for that. You need to find a plugin for that.

3. You can disable Wishlist and Compare from Theme Settings >> Shop >> Wishlist. And Theme Settings >> Shop >> Compare.

4. Please try adding the following Custom CSS in the Global Custom CSS area under Theme Settings >> Custom CSS.

.product_meta .sku_wrapper {
display: none;
}

5. You need to find a plugin to create an inquiry form and then you can change the content of the Shipping and Delivery from Theme Settings >> Single Product >> Tabs.

Best Regards
