Yes, even from 3rd party repos like frpm-fusion and google-chrome
cache. The correct line is:
keepcache=true

I don't know which effects has keepcache=1, I don't use this since
last time I used yum.

Yes as long a storage permits it or as long you want to keep it, a
"dnf clean all" will delete all of the packages stored on the cache.

I don't know, this is the first time that I hear of
python-dnf-extras-local, not sure what it does or for what is intended
for.

In yum days... yes, now days... yes, but I don't know if it is
possible to create a local repo, in a usb for example, starting from
these files.

Sorry, my bad, what I mean is:
1. You install a package foo-1.0.fc23.x86_64.rpm
2. The package is running on your system, version:1.0, and also the
rpm file from which you installed, is stored on /var/cache/dnf.
3. An update come, foo-1.1.fc23.x86_64.rpm.
4. After updating you end up with: foo-1.1fc23.x86_64.rpm running on
your system, foo-1.1.fc23.x86_64.rpm stored on /var/cache/dnf/
alongside foo-1.0.fc23.x86_64.rpm.
