Two bosons (non-composite) can occupy the same state, including the same spatial location. When they do, they are identical.
[guess]
So, for a particular system, you cannot know the number of bosons by counting. Counting does not work when you have no way to avoid double-counting.
To distinguish among different total numbers of identical bosons, you need to check, for example, the total energy of the system.
