Formatting multiple headings on a document

[Lone Eagle]

Hi everybody.

I have two documents, as shown in the attached image. On the left, there is the table of contents generated by the text on the right.

My goal is to have the first document formatted in the same way as the second one.

(Therefore having all the ABC-level headings in document 1 formatted in the same way as the ABC-level headings in document 2 - which is Heading 1 style,
All CDE-level headings with Heading 2 style, etc.)

Considering it's a long document with multiple headings, is there a shortcut to do it once and for all of them?
Also, why is the style's bar different in the two documents?

Thank you.
