OK- Here is what I see now from your test kit pics:
Ammonia 1 ppm
Nitrite 0.50 ppm
Nitrate between 5 and 10 ppm. (Nitrate readings from 1-20 ppm are the least accurate for this test kit)
Now comes the boring part. Do nothing for the next 24 hours and then retest and report the readings. Do not add any ammonium chloride. What we are looking for here is any change in readings. Here is what I would expect to see when you test again: Ammonia lower, Nitrite higher or the same but not lower and Nitrate higher.
Here is your "homework." Using the volume for your tank adjusted for non-water contents if you do not know the actual volume. Then figure out what it takes in terms of ammonium chloride to produce maximum of 3 ppm of ammonia in your tank. If you are not certain, it is better to be adding too little ammonia rather than too much. It;s like salting your food, if you add to little you can add more, if you over salt you are not able to unsalt. Over dosing ammonia mean oops big water change again.
Bear in mind when cycling a few things are happening. Different bacteria thrive of different levels of ammonia. If one raises ammonia levels to high in a cycle, you attract the bacteria that thrive on level much higher than a going tank produces. When the tank gets stocked there will will too little ammonia for those bacteria and there will not be anywhere near enough of the bacteria that thrive on tank ammonia levels and you get a spike. The same thing applies to the nitrite bacteria. And not only is this true in terms of ammonia levels, but it also applies for salt water vs fresh. The ammonia bacteria are not the same in these different types of water.
Where you appear to be now is at least half way, and likely more, through the cycle. If you had a chance to read the article to which I linked you in the PM, you should see that it takes only about 5 additions of ammonia to cycle a tank and that one of those is a smaller snack dose. Even a stubborn cycle should not need more than another one or two additions of ammonia. Moreover, the maximum ammonia level one reaches during a fishless cycle should never exceed 3 ppm. There is no reason for this.
There is a difference in how a fully stocked tank creates ammonia and how it is added in a fishless cycle. In a fishless cycle we raise ammonia levels in a single big dose. Basically, a tank goes from 0 ppm to 3 ppm in a matter of minutes. In a going stocked tank it takes a many hours to produce the equivalent of that much ammonia. The bacteria will handle that ammonia and nitrite as it is being created. Moreover, the amount of bacteria in any tank will always size to the level needed to handle that level of ammonia/nitrite. Add more sources of ammonoa and the bacteria will multiply. Remove some of the ammonia sources and the amount of bacteria will decrease. In a fishless cycle we are actually producing more bacteria than will be needed when the tank is fully operational. Better safe than sorry
