There are loads of different types of intelligence
I think that's both a simplistic description of things and difficult to prove, without some means of being able to read people's minds. We can observe and measure the ways people behave but we aren't currently capable of directly observing how they think. Safer to say that there are different areas in which people could potentially apply their intelligence and most people (for whatever reasons) only do so in a subset - some a broader or narrower range than others.
The other thing about intelligence is that how you apply it is shaped by your life experiences.
Yes. Also by your personality. One member of my immediate family has a reasonably high mental potential but has been (both by nature and by choice) thumpingly anti-intellectual all their life. Quite competent in a narrow range , functionally a moron in most other respects.
