Yes.

I don't understand what you are saying above.

However, the posted rules file indicates you are using multi port
ethernet cards (mac addresses are in sequence).
Also eth0 mac address != eth5 mac address.
Please state your problem clearly. What you kind of hardware you are
dealing with, what are you doing with that hardware.
Brute force solution - empty the persistent net rules file and reboot.
udev will recreate the entries in the file and assign device eth*
names in the order it sees them. Edit the file to your liking i.e.
which NIC (aka mac address) you want to assign to respective eth*
names.
