Educate me on the new terms associated with the Demeco Defense

I'm very old school with the terminology of Defense. In fact, I learned essentially a mirror defense where every offensive player was defended by a defensive player covering them. Thus C was covered by a Nose Tackle, Guards were covered by Defensive Guards, Tackles were covered by Defensive Tackles, Receivers were covered by CBs, and RBs and QBs were covered by LB and Safeties.

I know the terminology has changed and would like to know how to label the plethora of DBs we have by their modern position terminology.

This is where I start. Fill in the updates.

As much as i liked this, just tell me what each position is called now. It sort of looks like 4 LBs, though one could be a hybrid CB. Two safeties and a CB. But even the basic interior linemen seem to have new names. Edge seems foreign with almost any position capable of achieving that term.

This is our list of Defensive Players. Which ones are properly or improperly labeled at the position and which can be more specific than DB or DL?
