Speaking in general terms, 1mA is a low and acceptable value for quiescent current ("leakage"). Put into context, it'll take 1000hrs to drop 1Ah from the battery, that's 6weeks give or take.

Natural charge loss from a disconnected battery can be anything up to around 0.5% per day, so possibly in the region of 20% loss or 2Ah from a 10Ah battery in the same time.

If you're measuring way less than 1mA then it's fine. Anything down around 0.1mA is likely to be of the order of the accuracy of the measuring device, the difference between 0.1mA and 0.2mA is negligible.

I wouldn't worry too much about the winding resistance measurements, if they're all about the same and there's no path to earth, then check the open circuit volts between phases with the engine running (i.e. disconnect the alternator lead and measure between each pair of the 3 wires). If they all read about the same, of the order of 70V(ac) then all is well. Open circuit volts can vary quite a lot, 50-90V(ac) is probably a sensible range to expect but they should all be more or less the same between each pair.
