What are my chances?

I assume they're chicken eggs -- which usually hatch in about 21 days, give or take a day. I'm not familar with a Little Giant -- I use a Hovabator -- but are you sure it's supposed to hold water? Mine has a tray that goes in the bottom with water channels in it. The bottom of the incubator itself has vents in it so it wouldn't hold water.  I don't use the water tray. I use condiment cups. In my setup, two condiment cups of water holds the humidity at about 35%. On day 18, I put four cups in to bring the humidity to about 68% and once the chicks start hatching, I take one cup out. The newly hatched chicks are wet and increase the humidity, so I have to remove a cup to compensate and keep the humidity around 65-to-68 percent.

Edited to add: To increase humidity, you have to increase the surface area of the water, not the depth of the water; if that helps any.

That actually helps a ton. I was not filling all the channels just a few. I also only put one sponge in there assuming an increase in humidity would just be all around. I didnt realize surface area made a difference. Only one hatched

It isn't a failure unless you don't learn from it. If you learned something from the experience, it becomes another step forward.

Did you open the remaining eggs to see what happened? It can be helpful to see at what stage of development the chick stopped forming.

At this point, I'd clean out the incubator and set it up again. Run it and then see what you need to do to achieve different levels of humidity. I use condiment cups; it works for me. You can use sponges of various sizes or try filling the water channels one at a time and see how the addition of each channel contributes to the humidity. It might take a few days or a week of testing before you feel confident what you need to do to hold the humidity at the level that you want for days 0 through 18 and then 18 through 21. Remember that for 0 through 18, the egg turner (if you have one) is running and that will affect the environment inside the incubator. Do your test with the turner on and with it off to see the difference.

Once you determine what you need to do with your incubator in your environment, make a note of it. (You might not need to do this; I needed to because my memory is not what it used to be.) I have my 'instructions' written on a piece of cloth tape taped to the top of the incubator so when I pull it out again next year, it is right there to remind me what I found that worked.

I definitely learned from this. I did, it was a mixture of development day 18 or no development at all. The eggs I tried were not the best. I will definitely keep trying. However just today one of my hens decided to get broody lol
