Yes, your Norway visa is a Schengen visa. A Schengen visa is a short-term visa that allows you to travel to and within all 29 Schengen countries, including Norway.

You only need a multiple entry visa if you plan to leave the Schengen area and come back on the same journey or if you have several trips in a short time. You don't need a multiple entry visa for visiting multiple countries in the Schengen area during one trip.

If you are an Indian citizen arriving at Oslo airport from a non-Schengen country and have a connecting flight to another non-Schengen country, you may stay within the transit area of the airport. In this scenario, most Indian travellers typically do not require a visa, as they will not cross the external Schengen border.  Please note that if you arrive at Oslo airport for transit purposes, the transit area is closed between 11 p.m. and 6 a.m. If your arrival and your connecting flight's departure time necessitate staying at the airport between 11 p.m. and 6 a.m., you won't be able to use the transit area during this period. Instead, all travellers will be required to go through border control to remain in the airport's non-transit area or at a nearby hotel. This means that Indian nationals who must have a visa when crossing the external Schengen border, as indicated in Annex 1 of the Visa Handbook, will require a Schengen visa even if they are only transiting through Schengen in Norway. Indian Nationals need to collect and check in their luggage at the airport during a layover (for example, when using different airlines), as they will be required to go through border control.

No, Norway does not offer visas on arrival to Indians. You need to have an approved visa prior to your departure.
