The minimum for those should be as high as possible, but realistically that might not be possible for you. There are acceptable thresholds for guns where you get the most bang out of your buck. For small and medium these are +1 and +4, and then stopping at +9. For BB guns, it's +2 or +4, or some pair of +1 and +3. You can stop at +9 pairs.

Planes get 0.2 AA per improvement level, and unlike other equips, decimals are not floored until after all the calculations.

If you have the screws though, and everything else is up to scratch, feel free to bump those higher as decimals do get multiplied with pre cap bonuses, so it can make the difference sometimes.

For details on stat upgrades from improvements refer to this site and the the wikia page

Depending on the difficulty you choose, the state of your equipment will vary, but keep working on improving everything gradually~!
