More specifically, is there any type of converging or diverging lens - either meniscus, concave-convex, or plano-concave or convex, which, when you reverse the direction of light incident upon it, that it becomes either a converging lens instead of a diverging lens, or a diverging lens instead of a converging one? In other words, is a diverging lens always a diverging lens no matter from which direction you shine the light? Likewise, is a converging lens always a converging lens regardless of from which direction you shine the light?
Thank you!

No. Converging lenses converge in both directions. Likewise as do diverging lenses.

no. lenses are say symmetrical so no matter the direction of light, the lens remains the same (at least converging and diverging lens)

no a property of light is its reversibility - if you change direction back along same path the light will follow exact same rout
