Ha, ha!!! No - my good lady did not poison me tonight. Thanks to all who had a go. No. 5 was well described as a 'meanie'.
They've all been solved.
1. don = dress; bill = ad; bill before don = ADDRESS (address a letter = direct a letter
etc.) (Charade type clue)
2. daddy etc. As well explained (haven't looked at your link yet P@).
3. OUT ON ONES FEET (cryptic clue)
4. BAGGAGE ('double' type. Both definitions from Chambers).
5. ("clue" for the clue) What is exposed or shown or brought to light? by the other part of the clue?
