It's simple.

As a normal user without any admin rights whatsoever, go into one of the blogs you have written, then hover your cursor on the dropdown button, found next to the Edit button. There, you will find a "Rename" option. Click on it, then rename your blog.

An admin or even a content moderator can do the same thing, but to any blog post.
