is it ok? or do I need more?

This is not a bibliography.
A bibliography is a formatted list of published (and unpublished) WORKS, not a list of people with a summary of their lives.

As far as length goes, it's fine. I also didn't catch any mistakes.

PERFECT!!!! and i'm learning that stuff in social studies also

Ok, you can't really post it on here because then I can't see if the page is set up right.

Also is it APA, MLA or what? Usually it would be lastname, firstname.

Uhhh... Are these biographies or bibliographies? I thought bibliographies are lists of references. Glossary perhaps?
To make it more formal, you can remove the "and finally" in Alcott's. You can put "noted for her novel 'Little Women'" if not.

If this is supposed to be famous women in history, than your A OK.
