Teaching younger alters how to talk to newly found littles

Hi! So I just learned that one of my alters (I don't know a lot of them) has the same name as my childhood friend who endured the traumas with me. I grew up with her but I have no clue where she is which makes me wonder if she actually ever existed.
Apparently, I have another little (which has the same name as me and seems to be me frozen in time) who is still friends with the childhood friend. Both are littles that we have but I'm feeling very gaslite because I seriously can't tell if the friend has always been an alter or not. It is making me question who from my childhood was "real" and who wasn't. It's very weird because I hadn't even heard her name since I was a kid.
I don't have the ability to talk with them and they are still trying to understand what is going on. These two littles are stuck in time and too young to grasp what is going on. Meanwhile, my older littles are super confused since they believe the friend still lives somewhere and remembers them. They are very well meaning and want to help. I'm worried that they are going to talk to the two of them before me and will freak them out. They aren't great at explaining and I don't want them to say something to make them hide again.
Any advice for how I can prepare my littles if they make contact with them before me?

Firstly I'd check the friend is real. Get facts straight.

There's no way for me to confirm if she exists or not I tried and its just been too many years
anyone who would know if she is real are people who i no longer have in our lives because they were dangerous

That's one of the biggest reasons why i worry about other littles meeting them first because it could confuse everyone
i just dont know a lot which is frustrating

Ok then proceed with "there was an outside person with this name. This little also uses this name" That's most sensible and less head messy. It could be an introject - a person you knew who has kind of been imprinted in your psyche for comfort.
