I'm 15yrs old and me and my sisters and brothers would really like to see our real parent's because we haven't seen them in a long time since I was 7yrs old.

I detest the term "real parents".

ALL parents are "real"--foster parents, adoptive parents, biological parents, grandparents, step parents, and any other kind of parent you can name.

If a parent cares for you and wants what is best for you, they are a "real" parent.

Because you are 15, you need to talk to your adoptive (or foster) parents about your biological parents. We cannot help you search until you are a legal adult.

Is there a reason you cannot ask them?

Where did they go, why are you not with them? Who are you with now and why?
