Hello,
To import a page from other demos, we recommend creating a staging site first so your live site remains unaffected:
https://www.wpbeginner.com/wp-tutorials/how-to-create-staging-environment-for-a-wordpress-site/
Once the staging site is ready, you can import the additional demos there and copy or export the pages you want to use on your main website.
Alternatively, you can use the WoodMart template library to import only the elements you need. You can explore and import templates directly from here: https://xtemos.com/docs-topic/templates-library/
Best Regards
.
