If you are using OpenStudio and have multiple spaces in a single thermal zone, an internal mass object will be made for each pair of surfaces that are matched by spaces within the zone. The internal mass object has an area and a construction. It doesn't matter for this what the floor area or number of people are.
Beyond internal mass made by matched surfaces within a zone you can also add internal mass using the internal load tab of OpenStudio. In addition to just defining an area, you can also define an internal mass area per floor area, or per person.
Lastly if you use interior partitions in your model you can check a box to have them export as internal mass objects.
