What is the significance to you of the packages being in the same
manifest? To Puppet, it matters very little. Do you mean they are in the
same class? Or could they be made to be?

You've confused me a bit there. Your question suggests that you want a
single file depending on all the packages, but the example looks like you
may mean multiple files, each depending on one package. Or maybe not. I
am proceeding based on the question rather than on the ambiguous example.

There is a variety of ways. If the packages are all in the same class, and
File['file2'] is in a different one, then you can declare the file this way:
file { '/path/to/file2':
require => Class['mymodule::manypackages']
}
Alternatively, you can use tags to recognize the packages in question, and
write the relationship like this:
Package<| tag == '<some-tag>' |> -> File['/path/to/file2']
Tag 'some-tag' could be explicitly declared on the Packages, or under some
circumstances it would work to just use the class name (which is
automatically included in resources' tags). With explicitly declared tags,
this can work even when the packages are in different classes or even not
in classes at all.
Or you can perhaps use resource defaults for this. That's more brittle and
more susceptible to unintended relationships, but it's easy to set up. To
do that, put this at the top of the body of the class(es) that declare the
packages:
include <class-of-file2-if-different>
Package {
before => File['/path/to/file2']
}
There are other alternatives, too.
