Some questions about free and pro version

Hi,
I need a plugin which
– works with WP pages as well as with posts (I have WP pages, no blog)
– shows aggregate ratings for the article on a page, i.e., readers of my pages can rate the article (without a written review/text)
– shows aggregate ratings and reviews on some pages with offered services, i.e., customers of my service can leave there a star rating and written review
– enables a short sentence from me below/near the star rating feature like “Rate the article with stars!”
– enables flexible placing of the aggregate star rating, because probably I will have to place it right below the H1 as only good place, due to my layout
– does not produce JSON-LD code by itsself compulsory ans inevitably which I do not control; on every page JSON-LD code covers a lot of things additionally to rating/review schema, so this all will be done manually by me, separated from display of stars/reviews

Is this all possible with free and/or Pro version?
Has the fee for Pro to be paid every year or only once?
Your FAQ say the Pro version is for only ONE website, but on the top of your site I can choose 5 sites with Pro!?

Is there a comparison on your site which shows free and pro version, i.e., comparing all features?

Thank you,

Martin
