I have a Canon 1100D and some accessory converters: a Kenko Video Tele Converter KVC-20 II 2.0x, an XIT Elite Series 3.7x AF telephoto lens, and a Digital Optics Japan 0.45x wide/macro converter. Can any of these be adapted to work well on my DSLR, or are they not worth using?

I will assume no.
The first one seems to be a filter mounted converter and you need to have a lens with the specific diameter to fit it.
By the looks of it, I don't think any DSLR camera lens are that small.
It looks like something you mount on a GoPro or similar.
The second lens seems to be as cheap as they get, https://www.amazon.com/Xit-XT5837XTL-58mm-3-7X-Telephoto/dp/B00B49LP1O
No, not worth it. The adapter is probably far more expensive than the lens.
The third is meant to put in front of the lens?

They create so much distorsion and vingetting that you loose about 30% of the image usually.
And since it's ~$15, I assume the optics is not the best.
Buy real lenses with the focal lenghts you want/need, even "cheap lenses" ($100) will most likely be better than this.
If I linked to the wrong product obviously I'm sorry, the answer may be different, but most likely not.

Probably not, and in most cases it isn’t worth trying.
These accessories appear to be front-mounted/video-style converters rather than Canon EF/EF-S mount teleconverters. Front-mounted converters only fit lenses with the correct filter thread size, and many are designed for small-sensor camcorders or compact cameras. On a DSLR like the Canon 1100D, they’re likely to cause strong vignetting, distortion, and softness.
The cheap 3.7x telephoto and 0.45x wide converters are especially unlikely to give good results; low-cost front converters often degrade image quality heavily.
The Kenko “video” converter also is not the same thing as a DSLR teleconverter that mounts between the camera and lens. Even if you could physically attach it, image coverage and quality would be a problem.
If you want more reach on the 1100D, look for a proper Canon EF/EF-S-compatible teleconverter or, better yet, a suitable telephoto lens. Keep in mind that teleconverters reduce maximum aperture (1.4x loses 1 stop, 2x loses 2 stops), which can also affect autofocus on slower lenses.
