I have seen photographic evidence of:
1. Blue 1, Red 2 Hero
2. Red 1 Hero
3. Red 3 Hero
4. Red 5 Hero
Pyros:
5. Red 1
6. Red 3
7. Red 4
8. Red 5
9. Red 6
10. Red 10
11. Red 12
12. Red 1 body with Red 3 wings
13. Red ? - seemingly unpainted bird with a blue stripe (?) running down the top of the fuselage from cockpit to nose (you can see it at the very very back in the famous ILM "line up" photo that made the Topps card). Note it has a red colored cannon body, so maybe this is 6, 10, or 12 mid-paint? Perhaps that blue line is the seam that's been filled?

Which leaves:
14. ??
Also keep in mind, Red 6,10, and even 12 seem to share wing cannons and other elements - it's all a bit murky still as to which came first and when, which is in line with various accounts of ILM reusing/recycling intact detonated pieces.
Also, one of them was smashed to bits according to the story of Dykstra slamming one on a table to show it's breakaway-ability!
