Ok, the only thing you need to be putting in the water is the water conditioner. PH stuff, meds, and ammo lock are not necessary and will mess with your cycle. As I'm sure you've realized by now, you've added way too many fish way too soon. Your options are:
1. Take back all but the danios and continue doing a fish-in cycle with just those. (They are the hardiest fish you have.) All while doing daily water changes and monitoring the ammonia levels.
2. Take ALL the fish back, starting over and doing a fishless cycle with ammonia. (See link in my signature for complete fishless cycling instructions).
3. Keep all your fish, possibly killing some of them, and trying to continue managing. Since you are still asking questions that are answered on my page, I'm going to assume you haven't read it. Please take the time to do so, it will explain a lot to you. You do need to be doing daily water changes of about 25%, even more if the ammonia levels get too high. If you do have ich in the tank, you should not move the fish around. The whole tank is already infected. You should slowly raise the tank temperature to 84-86 and leave it there for around 2 weeks, all while doing water changes and treating the water you add to the tank BEFORE you add it. I would not mess around with medications as they will probably mess with your cycle. Once again, all this water change and fish cycling information is clearly explained on my page.
