This puzzle is the Macmillan Cancer Support Quiz and it wouldn't be viewed as fair if the answers are just given out on here because everyone who has entered has paid a donation and are also in to win a prize.
If these are your last three clues, I suppose a hint would not be out of order but in future I would suggest you have a look through an atlas gazatteer for ideas.
In order of your entries:
1) Container
2) Anagram
3) Homophone
This has to be sent in the next 10 days.
If you are stuck on more clues, try the gazatteer advice.
