I'm friends with these 2 girls but they don't seem to know that i'm friends with them both?

we kind of all live in the same area so i'm meet both of them through there work and friends with them there , also seen them at bars here but they've never been at the same bar together.

i tried talking to the one last summer about the other girl and how i had meet her but she didn't seem to like get what i was saying or though i had meet another girl at that restaurant and not the one she was friends with.

so not entirely sure if they know that i'm friends with the other girl too , not entirely sure what will happen when i eventually see them both at the same time ,
