Hello is there a way to Display just the Name and Descirption of a person who is not in the Org directory in a people webpart? or are there any similar webparts that will let you display the internal staff as well as external people (who are not in the directory)
You could utilize PowerApps and a powerapps webpart to do this to some degree or a full page app as I do. If you are trying to do a directory I would recommend it for sure since you can build a gallery from AD users and then create a SharePoint list to house your external users to also add to that same gallery.
Anyway, that only works for a full directory, if you're trying to just put a who to contact type snippet, then I don't know of anything out of the box, might check out github SharePoint spfx webparts for something that might fit the bill there, or you could very well try to make powerapps work with a web part that looks good, problem is sometimes sizing it just right to fit dynamically in the section of a page.
