Answer 1

From man mc:

…to set the attributes exactly to those specified, you can use the [Set all] button, which will act on all the tagged files.

This command sets and clear bits to exactly this state (the state with [x] and [ ]).

[Marked all] set only marked attributes to all selected files

This command sets and clear marked bits (marked with *). I.e. it sets/clears what you changed flipping the bits from [x] to [ ] or reverse.

[Set marked] set marked bits in attributes of all selected files

This command only sets bits marked with *, it doesn't clear.
