If I may take a layman stab:

Spin period: how long does it take the pulsar to fully rotate once, ie. how often does it “flash”?

Dispersion measure: from our perspective, how much is the flash “smeared” across time and frequency vs. just being a narrow-band sharp pulse? This is a function of how much stuff (electrons) exists between us and the pulsar.

Spin-down luminosity: how much of the pulsar’s kinetic energy is being lost as electromagnetic radiation? Pulsars spin more slowly over time due to this, so how hard are the brakes being pressed?

Surface magnetic field strength: what it says on the tin, how strong is the magnetic field on the surface of the pulsar? Refrigerator magnets are 10-100 gauss, a powerful MRI might be 30,000 gauss.

Characteristic age: estimated age of the pulsar calculated by assuming a very fast initial spin & applying the known spin-down rate to see how long it would take to slow down to its current rate. Makes some “spherical cow” assumptions but should be a good rough estimate of its age.
