Panama, Nicaragua and SAR passports are handled in these two places?

Panama has the same address as you found. Other information is as follows.

Nicaragua's e-mail can't be found, and the address is the same as you listed.

I suggest you call the two countries for consultation. Ask questions at once. Embassies and consulates have always been slow to respond to visa questions, and may even answer irrelevant questions.
