Often I meet a snippet with a ranking in Google’s search results for articles and product pages, but I have never met for the main page. Can I add asterisks to the google snippet for the home page? Has anyone encountered such pages or are there any restrictions on the part of Google? For a one-page website selling one product this may be useful.

Of course you can do it. You can do this with the Review type from Schema .
However, there are some clarifications / limitations in the Google documentation for structured Review type data:
You can provide ratings for the following types of content: Local businesses + Movie + books + Music + Products .
Make sure that the reviews and ratings that you mark are easily accessible to users from the marked page. It should be immediately apparent to users that the page has a review or rating.
Thus, you cannot apply reviews from third-party websites and reviews should not be hidden from users, for example, in an accordion or in a tab.
And notice that the author property is required. This may be a person or organization.
In line with this, pay attention to the following Google comment:
The name of one reviewer must be valid.
In addition, in the General Structured Data Guidelines, Google informs that structured data should represent the main content of a web page.
Summarizing all the above, I can answer your question as follows:
If the main page has main content like a Local Enterprise or Movie presentation or a book or Music or some Product (for example, unique and / or handmade), then you can create structured data markup for the main type for both reviews and for type AggregateRating . At the same time, reviewers should have some kind of identification, for example, a link to a social network profile, or a link to a website or something similar.
