One consideration is focal length. I'm covered from 12mm - 300mm. I have a 1.4 Kenko TC, so make that 600mm. Aside from focal length, some people like certain lenses because of the quality or features. If you prefer to shoot with prime lenses, you may find yourself with a lot of them.
Looking at my list, I see I have ten lenses, covering Nikon and Sony.
I do prefer to use primes, that's a personal choice. I own zooms, but I felt they were making me lazy in composing. That's just me. I also own a number of primes but find that a 50mm and 300mm with a 1.4 TC are what I use most and are really all I need.
