Hello,
First of all, please, don’t post topics at the features forum https://www.8theme.com/forums/xstore-wordpress-support-forum/xstore-features/ because it’s only for the new option requests, if you need help with the existing settings then use main support forum https://www.8theme.com/forums/xstore-wordpress-support-forum/
1) Go to Plugins > disable Wishlist and Compare plugins.
2), 3), 4), 5) Use xstore theme and xstore core plugin translation files to translate all the necessary strings https://www.8theme.com/documentation/xstore/theme-translation/base-theme-translation/
6) “county”? Maybe you meant country? You can choose the option to sell to a specific country http://prntscr.com/rplu98 and then you won’t have selector at the checkout. If you need to remove any other field you can use Checkout Manager plugin because WooCommerce does not have advanced options for this.
7) Use one of the special plugins for these purposes, like WPML, Polylang, qTranslate or similar.
