Both of those objects could be collisional rings, with two of these forming

Not a collisonal ring, but a disrupted spiral galaxy.

Possibly a jellyfish

There is no cluster nearby so jellyfish is highly unlikely. The distance to this galaxy is roughly slightly further than the Virgo cluster.

Are these collisional rings examples of ring galaxies?
Mergers/Interactions Gravitational lenses

Collisional ring galaxies are a unique type of object out there.
These collisional rings usually form in a Mergers/Interactions. Unfortunately, fo the Gravitational lenses category. These CR-types form from a collision, Gravitational lenses usually form from an arc shape.
