For 1) here's a possibility:

In this chapter I saw Ingeel bleeding, a young child probably doesn't know how to check for a pulse, much less a dragon's pulse. They also probably don't know how much bleeding is lethal, so by not moving it looks all the more real. Sting and Rogue were only kids back then.

Considering how long it takes for a body to turn into bones its quite possible they used that to fake being dead. This also helps Sting with bathe in his dad's blood to become a "true dragon slayer", and Skiadrum could have easily faked his illness since Rogue likely didn't know anything about dragon diseases.

And if all the Dragons have been inside their children like Igneel, then one night after being "killed" they went inside them. Since they'd have been asleep during this time they wouldn't have noticed. And since they were "dead" they had to wait until they knew Sting and Rogue were too far away to notice their bodies had disappeared. (Sting and Rogue likely wouldn't have stayed to even check, it would have likely been too painful for them.)

For 2)

Well... I actually don't have any ideas for this one, but Robaul was using his magic. And Atlas Flame's magic seemed to have been depleted too much due to Silver's magic.

And for 3)

There is one way around this one to give more sense to it, they weren't eggs at the time. Plus if they had been eggs they'd be baby dragons and wouldn't be able to help, plus they may have told their children they would have their slayers kill them so they didn't say anything on purpose.

In fact its possible maybe the Weisslogia and Skiadrum that were elderly weren't the real ones, there are many dragons for each element, so its possible that they had sent substitutes or even illusion similar to Robaul in their place just for a moment like this. Recall we still don't know the reasons the Dragons even disappeared during 7/7/X777 so we can't really understand anything the dragons have been doing.

I agree, judging is too hard right now, but making theories can sometimes help show us the answers.
