Best alternative to Nikon 14-24, 24-70 and 70-200mm?

Looking for the best alternatives to the Nikon 14-24, 24-70mm and 70-200mm? Currently using a d90.

Added (1). Alternative as in cheaper but close to. I. E. Sigma.older Nikon alternatives like 28-70. Asking for opinions as I have searched forums but trying to see if I missed anything. So far I'm considering the tokina 11-16, nikon 28-70, and 80-200.

I don't understand what alternative means in this case - other brands, other sizes, what?

Other brands there aren't any as good. Other sizes they're plenty just do some research.

Alternatives to 14-24mm lens:
- Sigma 10-20mm f/4-5/6
- Tokina 12-24mm f/4
- Tokina 11-16mm f/2.8
- AFS Nikkor 10-24mm f/3.5-4.5G

Alternatives to 24-70mm lens:
- Tokina 16-50mm f/2.8
- Tamron 17-50mm f/2.8
- Nikkor 17-55mm f/2.8
- Nikkor 16-85mm f/3.5-5.6 (if you're willing to settle for smaller f/stop)
I would skip 24 or 28-xx standard zoom lenses because the wide-angle isn't nearly wide enough on DX cameras like the D90

Alternatives to 70-200mm lens:
- AFS Nikkor 70-300mm f/4.5-5.6
- AF Nikkor 80-200mm f/2.8D
- Sigma 70-200mm f/2.8
- Tamron 70-200mm f/2.8
