Eleven,

Why post five puzzles in one thread? Things can get pretty confusing if there are a number of replies about different puzzles. I've seen confusion when there are just two puzzles in the same thread.

The reason is, that they are very related.
But i guess you are right, so i will distribute them to Muggy 2-6.

The title of this series of puzzles strongly suggest a specific pattern of interest. Thus......

Two overlapping AURs: AUR(47)r12c48 & AUR(34)r28c78 with common digits (347) and a single internal reference 9r2c8 which completes the puzzle.

Well done.
That's why i like DP's.
If they are there, you can spot them in 5 minutes from a pencilmark grid.
