Share on Facebook. Change "say something about this", multiple buttons on one page
I know I can use a meta tag ob:description
to change what is displayed by default to "say something else about this" when the user clicks the Facebook share button.
However, I add several dynamic sections to my page (this is a SPA application), each of which links to a different url, however, how can I assign a different "say something about this" to each one if I can I add a meta tag only once?

What you want to change is the user's message, right? ("Say something about this ..."). Which is not generally possible in the Sharing dialog, and in any case it will not be allowed according to platform policy :
2.3: Do not fill in the subscriptions, comments, posts or posts of the user parameter posts with content that the person has not created, even if the person can edit or delete the content before sharing.
