Below I have modified a picture of yours and color coded it so we can talk about the different areas. Now, remember, this is just my opinion and it's only meant to be educational. Others feel free to chime in.
The RED circle: This egg is WAY too wet. In fact, this egg will probably start to grow mold. I had several eggs that looked like this just before they died. If you see mold, try to put some anti-fungal powder on there and hope for the best. If it starts to smell or feel FIRM, throw it out. By firm I mean like a soft boiled egg. The yolk will start to harden and it will be a definite firm, immovable touch to it.
The BLUE circle: This egg is looking a little too damp as well, but not as bad as the egg above.
The GREEN circle: This is probably not an accurate measure of your humidity. Those analog gauges aren't usually very accurate. I would suggest you get a digital one that has a probe on it. if I had to guess, the substrate is too wet but the eggs are too dry based on the dimpling from the top egg. You can try to put a layer of press-n-seal on top to trap in the humidity.
The ORANGE shading: Because your eggs look a little too wet, I would get them up off the substrate (that may mean you need to change containers) and put them on a light grate. You can buy it at Home Depot. it comes in a large sheet and you'll just have to cut it down to fit your tub.
Hopefully that helped a little bit and hopefully you can save several of those eggs.
