Yep, nice, lots of references to this. You can also see the counter arc towards the bottom of the image.

Do lenses manifest into an oval-shape with the help of another galaxy? Can multiple galaxies make the lens wilder, especially lensing galaxy clusters?

Yes, I believe so. I looked up a few papers and I seem to agree with these publications, lenses can sometimes manifest into almost wrong positions because another body is influencing the light patterns of the whole gravitational lensing system.
