First of all, if your system is working fine, in particular all your wired and wireless network connectivity, then you don’t need to do anything — those are only warnings. Some modules will work fine without firmware in most cases (the e100 module), others will typically require firmware; the specifics depend on exactly what hardware you have.

If you do have networking equipment which doesn’t work properly, then you should install the appropriate firmware. In your case, the packages you need are firmware-misc-nonfree (for the e100 firmware), firmware-netxen (for the netxen_nic firmware), and firmware-realtek (for the r8169 firmware). To install these, you’ll have to enable the non-free repositories; to do so, edit /etc/apt/sources.list, find the lines which looks like

deb ... stretch main

(with a URL instead of ...), and add contrib non-free:

deb ... stretch main contrib non-free

You can do this automatically by running

sed -i.bak 's/stretch[^ ]* main$/& contrib non-free/g' /etc/apt/sources.list

as root; this will make a backup of your original file as /etc/apt/sources.list.bak so you can revert if something goes wrong.

Then update your indexes and install the missing packages:

apt update
apt install firmware-misc-nonfree firmware-netxen firmware-realtek

and update your initramfs:

update-initramfs -u

You might need to check if a specified package is installed or not:

sudo apt-cache policy firmware-linux-nonfree

Then you to install the missing firmware run:

sudo apt-get install firmware-linux-nonfree

After which you can run your:

sudo apt-get update

This should help.

    Just a clarification: apt-cache policy won't enable anything: it only tells if a specified package is installed or not and what version(s) would be available in your currently configured repository(/ies). If there are multiple versions available, it will also identify which of those would be the "primary" installation candidate according to your current apt preferences. – telcoM May 24 '18 at 06:47
