Can I extend my 30-day visa exempt entry multiple times in different provinces in Thailand?

So a visa exempt entry can only be extended ONE time for an additional 30 days.

Currently there are "60 day covid unable to travel extensions" that is a separate extension from whatever visa you are or where on. The only extensions that require you to use the same office twice are yearly extensions of stay, or extensions where you're given an initial "under consideration stamp" and told to return in 15 days.

Finally, No. Visa exempt entry, tourist visa, or covid extensions do NOT require health insurance or onward proof of travel to extend.

nope, 😕 When you enter on a visa exempt entry you can extend it ONCE for 30 days for 1900baht at the immigration office where you stay in thailand.

Then you're done, unless they are still offering 60 day covid extensions (which they will do until Nov 26th).
