If you live in Phuket, can you apply for extension of retirement visa and none immigration B visa in Bangkok or must you do it in Phuket?

You must do in Phuket.

An extension of stay based on retirement should be requested from the Immigration Bureau office covering the area in which you reside. Non-Immigrant "B" visas are issued by Thai embassies and consulates outside of Thailand. Are you intending to change your visa type from "O" to "B"?

No. I have a non-immigration "B" visa (thats what i think the name is , i have it for many years because i work in thailand, and every year I extend it by the immigration in Thailand)

The other visa "retirement visa" is for my mother.

Actually you have an extension of stay for work rather than a visa. The visa was only for your initial entry.
