The people are overtly named by God, in just a verse or two, at the beginning of the book, but the book is called Names for a reason that pervades the book as a whole. It is as if the name of the book were saying: God continues to know our names, to keep track of each and every one, throughout all the events that happen in the book.
Just like creation is woven throughout the events of Genesis, God continues to know the names and stories of each individual through slavery, escape, and wandering in the desert because he cares so much about each of us
