I'm going to try to come up with something to put in each group, but it might be pretty scant.
1) 6-8pm Sunday
I believe someone posted previously that the plane landed about 5:47 pm (I'm not positive about that time, I know it was around 6:00). He would have to be picked up by his father according to the rules for children that age flying. Nothing has been said about any luggage other than the backpack. He texted his mother telling her he arrived and his dad was there to pick him up, I believe. It sounded like it was sent while he was still in the airport, so I can't see anything happening to him before that time. He "talked" to at least one friend, but I believe it was just texts.
They were expecting him at 6:30 am, so he may have told them that then. From what the friends say, he may have also told them that he'd hitchhike if he had to, but I'm not sure if that was confirmed or just speculation. They haven't confirmed where the shopping was done as far as I know. They also haven't said how long they were in there. I was wondering if they had gotten something from the deli to eat that night too, since he got there so close to meal time. No video of them anywhere has been shown or mentioned that I know of, but that does seem strange to me. They have asked for any video anyone might have of the road they were on during certain hours. I don't believe it's ever been said what time he told them they got home. Nobody has said where he says they were at 8:00. He may not even know if they just did the shopping, went home and went to bed. I don't believe anything was said about where the last ping/call was from either.
2) 8pm - 7:30AM
What's been said is that they shopped, went home and slept. MR got up early and got ready to go, and tried to wake DR up. He said he made noise, which could be anything from turning on a tv or shutting a cupboard door loudly to banging a spoon on a pan, etc. He says that Dylan didn't get up, which I'd guess means he told him to leave him alone (or to knock it off) and went back to sleep. When he still wasn't up by 7:30, MR left.
I was wondering if DR woke up after dad went to bed and maybe played a game for a while or something (even if he could get a cell signal, it may have been too late to be sending messages to friends.) It was said that they went to bed/sleep when they got to the house,
3) 7:30am - 11:30am
It was said he had 2 meetings that morning, one with his attorney, but I haven't heard who the other was with. Somebody said it was about a 2 hour drive there, maybe longer, but if that's the case it would have taken much more than 4 hours. I've read somewhere that LE has confirmed his appointments/time gone. No idea about the rest of the questions
4) 11:30am - 4:30pm
He said he got home at about 11:30. He said he told the police the first day that the fishing pole was missing, so he may have looked around the place to see if he could figure out where he may have gone. I'd guess that was after he learned that he wasn't at the friend's house. I'm wondering if he even realized there was a problem before he went to the friend's house to get him and found out nobody had heard from him. I know I read that he looked around for him, and called his ex-wife after he got back from the friend's house. I think it was about 4:30 when he called her, and about 6:00 when he reported him missing.
I know, this wasn't much help, but my eyes aren't focusing real well again.
