Is it okay for me to use Nikon AF-S 24-70mm lens on my D7000?

Is it okay for me to use it because right now i'm going to buy some new lens. Give me also some suggestion on other lens that are good for Nikon D7000.

YES! That is a good lens. Do it!

The 24-70 is one of the best lenses on the Nikon lineup

Why wouldn't it be OK?

Yes but to learn more about Nikon lens compatibility, check this page.

You just can't get suggestions for a new lens. You have to decide on it yourself. To know how to select lenses properly, see this page.
