You need to put attribution about the origins of some of the code in
the NOTICE file for your app. On an individual header, you can just
add yourself as an author/copyright holder. If the original step file
is lacking the license header, please let us know, so we can add one.
Even in their absence, they are covered by the Apache 2 license.

You can absolutely put some text in the header file saying that your
new work is based on the old work, and the original header is below.

You can re-use the work without having to get the agreement of the
original authors, as long as you're not going to be changing the
licensing terms at all (ie: you release the final derived work as
Apache 2) *and* you don't modify the fact that the code you are
incorporating remains copyrighted by the original authors.
The Apache License grants these rights to those who receive a copy of
the software.
Happy to help,
