You can have a range of anything, so long as the subjects in question really are a range, i.e. examples at the ends of a clear continuum, even if it's only alphabetical. E.g.
There were a wide range of volunteers, from young teenagers to retired doctors.
The respondents ranged from Anthony Adams to Zephania Zahid.
A wide range of specialists working in the area include a heating engineer and two nurses ? The people involved range from Mr Smith to Mr Johnson
I thought I'd done that in #2. But here are a few more:
The shop sold a range of vegetables from tiny onions to giant marrows.
The suggestions ranged[yes, it can also be a verb]from the sublime to the ridiculous.
The main sequence of stars ranges from blue giants to red dwarfs; white dwarfs fall outside that range.
This last example may help you best if you compare it with a Hertzsprung-Russell diagram.
