What are the alternatives to the tamron 20 40mm f 2 8 di iii vxd?

I can't give you a reliable list of named alternatives to the Tamron 20-40mm f/2.8 Di III VXD. Its page covers the lens's mounts and the cameras it fits, but it doesn't list other lenses to compare it with, so I'd rather not guess at models.

Here's what I can point you to. The Lenses page covers third-party makers like Sigma, Viltrox and Samyang, and what to check before buying one. If you're choosing by focal length, the Portraits guide explains the 35mm, 50mm and 85mm options. The Focal length converter will help you work out how f/2.8 translates on your sensor.
