Oh ok. Your tank is improperly stocked I think, so you really need to make sure your water parameters stay stable, and that means frequent water changes. Your fish died because the carrying capacity of your tank is not enough to support all those fish, so the number of water changes you were doing were not enough. Or the tank was not cycled.
Please look up profiles for each of the species you have, just to get an idea of what their needs are. Different fish prefer different types of water, temperarures and have different feeding habits. Ideally this research should come before stocking the tank. There's not much of a point in keeping fish that do not display normal behavior i think.
There are lots of healthy stocking options for 10g tanks out there. I've used a few male guppies/1 betta/ 2 platties/ a group of male Endlers. Those were not in the same tank, they were separate tanks. A group of pygmy cories works too, since they are really tiny! There are lots of options, but each requires extensive research to make them work. 10g are more difficult to keep than larger tanks because there is much less of a cushion when your water parameters change. So please be diligent with water changes. I do 2-3 20% water changes each week, and I always get rid of uneaten food each day.
This forum has lots of resources for new fishkeepers, so please research as much as you can to provide your fish with the best possible home and to provide yourself with fish in the best health
