What are the alternatives to the ttartisan 40mm f 2 8 macro?

The closest match on this site is the TTArtisan AF 40mm f/2. It's a 40mm prime for full-frame cameras, so it keeps the focal length but gives you a full-frame view and a wider aperture. It isn't listed as a macro, so don't expect close-up work from it.

For real macro, I'd look at the Canon EF 100mm f/2.8 Macro USM. It's a full-frame 1:1 macro and a common used alternative to the L version. The longer focal length gives you more working distance from your subject, which helps with insects and other skittish subjects. The catch is that it's an EF-mount lens, so it's for Canon EF bodies rather than the mounts the TTArtisan covers.

If you're comparing across sensor sizes, the focal length converter explains how crop factor changes depth of field.
