Should I talk to the new coworkers?

So my supervisor was a narcissist. He then sexually advanced and I finally snapped and went to hr. They separated us.

A few things, The first time we met he told me he likes to mess with younger women. I think I became his victim cause I threatened him. I was loved and good at my job. He wanted me to quit or get my fired. Idk if he's done it to anyone else? The girls he trains now are young and not threatening. Idk if he's ever done it to anyone at the company? No one has said any indicator that he's been bad. Other than the director who called him a narc to his face.

We got new girls, young girls. Passionate girls. To replace me cause they're making me switch teams. So I'm training them. But the reason I told on him was to protect others but he's still directly involved with them! This one is very knowledgeable but really direct. She seems autistic which I think for me I'm more empathetic so he exploited that. Idk how narcs and autistics are? Maybe that makes her more of a chance to be taken advantage of?

I'm worried. I was thinking of saying like if anything happens you can talk to me? Or idk? I don't wanna create drama. But people should know? And I'm scared for them. No one else has said anything, so either he really just hated me, or I'm the only one who was able to speak out. And I wanna help others do it. Anyone have experience with this? We're a small company
