Unfortunately, most of your feeds are not prepared for import. all of them have the same issue. Unfortunately, woocommerce requires to have price for products and price must be in universal approved format with dots. Most of your feeds have not prepared price format. They use symbols like $ directly in price instead of separate field for currency, many of them have no price at all or use symbol like "-"
this is also wrong way - you can't use currency in price field of woocommerce
also many feeds uses strange symbols in names https://monosnap.com/file/ftOAm8cfSNcvYqy2sv9OJltSND2uvj they are restricted for wordpress
Anyway, you can import such not prepared feeds in posts. You can't have price comparison with such feeds, but you can have deal site. Posts doesn't require special price patterns as it's simple text field, so, you can import anything to posts
