Look up the latitude and longitude of a place with Geocoding API

Hello. Is it possible to get all the countries, states and cities in a region/polygon drawn in a map? Could you please help me out.

Thank you

Pin map

Can you help me out

Nit: Retrieving an Address for a Place ID (placeid->address+latlng) is not Reverse Geocoding (latlng->address)

Could you please make an episode about how to drop pins on a map and get the addresses and lat/lng?
