Can I get multiple re-entry permits with a NON-O marriage visa in Thailand?

You could, but why would you? Are you planning on leaving 4 times during your 90 days? That's the only way it would make sense, because a single re-entry costs 1000 baht and a multiple re-entry is 3800 baht. A re-entry permit is only valid until the end of the stamp you purchase it on. So if you're on 90 days now, the re-entry permit will only be valid until that ends.

You can purchase a single re-entry permit at the airport on your way out. After you get the annual extension, purchase the multiple re-entry from immigration.
