Minors are not allowed to adopt.
only if your brother or sister adopts it
No, because in the eyes of the law they are considered brother and sister.
Yes. You can probably adopt your brother's or sister's children. You may need to check with a lawyer. There is a family services agency in your area that is familiar with lawyers who handle that type of law.
Adoption is usually used to establish a legally accepted parent-child or custodial relationship. If your sister-in-law is a minor without custodial parents, it might be possible to adopt her, but as your child, not as your sister. Consult an attorney familiar with adoption law in your area, petition the courts and see if it works.
A biggy is like a big sister or brother for a pookie. A pookie is a baby found in the pet shop. When people say "FREE BIGGY" it means they want a mumu to adopt them and be the big sister/brother of a pookie.
well after the age of 18 it is unlikely for them to be adopted even as a younger sister/brother. You could call her/him your younger sister/brother but it would not be official
It is not "wrong" to have feelings for each other that are more than brother and sister. However, it may be best for you two to try and remember that you are now brother and sister and try to keep your feeling for each other on that. Talk to each other about it and then go from there. Just keep in mind that you are brother and sister no matter if it be by blood or by paper.
It is certainly possible, but it is not just his choice, there have to be appropriate measures in place to provide support for the child, now legally his.
Your sister-in-law can never become your sister. However, if your parents adopt her legally (most unlikely) she might become your adopted sister. If your husband's brother marries your sister, then your sister will also be your sister in-law...
Yes all three were adopted legally.

Yes, with your parents permission
