Are these eggs still ok?

So I have a hen that decided to go broody about 16 days ago... She had a batch of eggs she was sitting and the nest was tilted so when she moved they all rolled out and broke at day 6.... So I made her a new box and gave her 8 eggs to hatch so we are now on day 9 or 10! They are definitally developing except for 1 that was obviously never fertilized and 2 that's shells are too thick and dark to see anything at all, no light shines through.... But I candled a white egg of mine and I could see movement! It was amazing! But I'm going to post am some pictures of eggs im pretty sure are still alive and developing and one that is questionable to me.

Alive:

Questionable (both same egg):

The questionable egg has veins my camera didn't want to pick them up... All the eggs had lots of nice healthy looking veins
