With alnico magnets is there a way to tell if it may be a 2, 5 etc.?

If you have both, one will be a lot stronger than the other.
Before I got a guass meter I used heavy steel weights.
I knew how much I could pick up with a fully charged A2, A3, A5 Bar magnets.
A3 being the weakest, A2 a little stronger, and A5 is much stronger, C8 stronger yet.

How would you tell a well-charged A2 from a degaussed A5?
Charge is not a good indicator of AlNiCo grade. I think it's been discussed here ad nauseum that the only real way to tell is by a lab analysis - right?

Metallurgy Analysis is beyond the scope of this B/H Forum.
Probably most asking this, are using limited resources.
Sounds like my Shop, I do a whole lot with very little. lol
Most cheaper factory pickups use A5, and C8.
Some use A2, but not many.
If you can recharge the Alnico bar magnet with NEOs, and the Alnico Magnet is fairly strong, it is probably A5.
