Once again, I think I'll go backwards from most recent first, focusing on TV/film this time.
The Gifted
Played by Emma Dumont, this was the very first (and so far only) time we've ever seen Lorna in live action. Dumont became a big fan of the character as she played Lorna, and it showed as she did amazing with Lorna in season 1.
Wolverine and the X-Men
In this cartoon, Lorna is on Genosha as part of the Magnus family - which includes Wanda and Pietro. This was made in 2009, the latter half of the same decade that brought us Genosha and the family. It was made before the retcon on the twins' parentage happened.
She has an almost-romance with Gambit for one episode. In another episode, we see future Lorna deeply traumatized, living in the ruins of Genosha after it's been destroyed, wearing her father's helmet.
Unfortunately, it only lasted for one season. It had plans for 3 seasons, but then the Disney buyout happened and all the X-Men projects got shut down.
X-Men 90s animated series
I'm including this for completeness sake. She was in the 90s TV show for a couple episodes. I can't say too much as I never really watched it.
