answers are all tube stations
1 Make 'em sick (5,5)
2 Would you find a branch of Lloyds bank here? (10,4)
3 Cockney Rabbit 'ole (7)
4 Regal open spaces (6,4)
5 Prepare for a siege (9)
If you have the wrong number of letters for number 1, (I think it should be 7 and 5, not 5 and 5) I suggest Turnham Green, as I think I answered this for someone else some time ago.
