I am sure you have better eyes than me and more experience...but agree it is likely behind.
Overall looks like some viable eggs, just a pretty staggered hatch
I would say a definite not fertile on #6
#8 and #5 seems to be not as far along as the rest by at least a few (if not more) days.
#7 seems to be right ahead of 8 and 5
#9 and 10 are hard to tell--not sure if it is because of shell color or they are full of baby chick
#2, 3 and 4 look to have...
I would say #1 for sure and then there was one that looks pretty porous and empty-I would have to watch again to give you the exact number-I can if you want.
I also saw one that looked closer to a day 5/6 not 12-15--is there possible a staggered lay date? Again, I can't remember the number...
I think I see one for sure that might be viable (time was 1:15), but I agree with above, give it until day 7-10 and try candling again. if you can get a strong flashlight and use a toilet paper tube (or similar) that might be easier (and give a better idea) than your phone-just a suggestion
