It depends what you're airbrushing.
The 2nd one are good for airbrushing water-based acrylic paints only.
If you're airbrushing solvent-based paints like lacquers or enamels you should look for A2P3R cartridges.

Again, it depends. But generally for P3 mask it's until you have difficulty breathing.
P3 filters are "passive", while Ax filters are "active", hence they have a shelf-life once opened. Generally that shelf-life is 6 months or until you can start to smell the solvent, whichever comes first.
One important thing: for wearing a mask, rules is that must not be any facial fair, which can be tricky if you're male and wear a beard.
