Even if I add water, the filter is still not cycled. So let me ask 1 thing. If a changed the water with my well water how do i still get the tank cycled with the fish in ti
A cycled tank means 0 ammonia, 0 nitrItes. All this once the tank is fully cycled, starts getting converted to nitrAtes. NitrAtes are not toxic to fish. It depends on the fish what levels they can accept, but it is good to keep them at 40 ppm max where possible, because high nitrAtes can cause another chemical processes in the water that can indirectly harm your fish(like sudden Ph drop).
To cycle your tank with fish, and if you want as many as possible to survive, you need to test the water everyday. If you detect any ammonia or nitrite, do a massive water change to bring as close to 0 as possible. For example you said you have 0.50 ammonia at the moment. If you do 50 % water change, that will bring it only to 0.25 % ammonia. So to make your life easier, do a larger whater change, like 80% at least. Take your time adding the water back, not to stress your fish additionally.
Tomorrow, test the water, if you detect any ammonia/nitrite, do another water change. And then keep going like that every day.
Eventually, the bacteria in the filter will grow enough to take care of the ammonia/nitrites and hopefully sooner, rather than later, ammonia and nitrites will be zero and NitrAtes will be on the rise.
It sounds hard, but you may already be at some stage of the cycle, as you already had it running for a while. And changing the water regularly may save some of your fish hopefully.
