Looks like you need to assign the featured tag to the posts.
Navigate to Appearance → Customize → Featured Content.
Enter the name of a tag.
Click the blue “Save” button at the bottom.
After that's set, then do the following:
Go to All Posts.
Click the box next to the 5 posts you want to show similar to the demo. There should be a checkmark.
In the drop down above the list of posts, change it to "Edit" and click the blue "Apply" button.
Additional fields will now be present. In the Tags box, type the name of tag you set up in the earlier steps.
Click the blue "Update" button.
When you refresh your home page, you should now see it matches the demo.
