Is the phrase 大人になった used here? And I was wondering when is it used? Do you only say it to adults or can you say it to older teens such as 16/17. Like in HS I would tell my friends to grow up or HS students say that to each other, (i.e if your friend plays with action figures or watches anpanman you'd tell them to grow up) so would they use the phrase or another one?

Yes, same as in English. "You've finally grown up, Lucy." Or "you've finally become an adult." Also, same as in English, age and what level of "grown up" depends on context.

So in context does it mean Lucy is meant to be an adult

I don't know the context. I haven't read this manga. This one speech bubble does not provide any context.
