The best way to be sure that water does not enter your Scuba dive tank when diving, is to never allow it to be completely be emptied of air pressure. Always plan to leave at least 1-2Mpa (10-20 bars) left in them to ensure that moisture does not enter.
If for some reason, the scuba dive tank pressure should be completely exhausted, it is important to immediately close the valve to keep moisture out. When bleeding the air from your scuba tank, be sure to bleed the air slowly, as quick bleeding may cause internal condensation.
You can't let it get in when you are breathing from it, but you can get it into your tank if you don't keep your cap on your tank. Another way is from pressing the button on your second stage, so it can get into your tank.
The numbers on a scuba tank reveal 3 things. Serial no. of the tank. Type metal. and the current hydro date.

I would think so, because there are two of them mixed together. Air in a scuba tank or anywhere else should be heterogeneous. A scuba tank filled with either oxygen or nitrogen would be homogeneous.
the silly answer is you can store anything in a scuba tank that you can get in it!!. BUTthe serious answer is scuba tank were designed for compressed air and nothing else... using a scuba tank for natural gas is like driving around with a bomb in your car!!, the valves and collars of the bottles are not strong enough if there was a crash
