I'd say get one or two or three lenses (if you can afford that) for your body, and use them a lot until you feel like you know what kinds of photos they take for you. I often use a "normal" length lens (e.g., 50mm on a film SLR which looks, because of cropping, more like 20-30mm or something on a DSLR or digital mirrorless with 4/3 sensor size--smaller than 35mm film size). I use something like that a lot. Prime (i.e., not zoom) sometimes gives you better optical quality, but there are some great zooms, too.
I also often want a 100-200mm zoom or telephoto, and a wide angle (that tokina is maybe a 20mm lens?). I rarely need anything more.
For lots of $$ you can get zoom that will do many of those things pretty well. For less $, you'll get a zoom that does none of those things particularly well.
