I believe CO has the youngest fleet, while we all know NW is the oldest (but very, very well maintained).

CO probably has the youngest fleet in the US. Worldwide, it sort of depends on who you count as a legacy carrier, but SQ is way up there.

Co and NW respectively, I believe.

I just flew on an old NW 757-200 (DTW-BOS-DTW) and enjoyed every moment of it. Very well maintained AC, unlike the old DL 757's I have been on.

Please don't kill me for this silly question.

Are they parameters to measure if an aircraft is young or old? (e.g. more than 5, 10, 15 years, or depends of maintenance, or other factors).

at you can find fleet age of all airliners (even per plane-type)

In the real world aircraft age is measured by two things:
Hours flown and cycles flown. Hours is obvious and cycles refers to a completed flight, ie a take off, some time in the air, followed by a landing is one cycles. Most component life and inspections are specified by either or both of these parameters.

These two parameters can be almost in sync to wildly different. The best example of the latter is JAL & ANA's B744D. They were delivered without winglets and configured for Japanese domestic operations. In this role they will obviously rack up a disportanate number of cycles for the hours flown. So they brought the winglets and as the airframes reach a high number of cycles they will add the winglets and reconfigure them for long haul ops where the hours will catch up with the cycles.

BTW have any airframes been so reconfigured yet?
