1.A bit like an itchy skin problem (8)
2. Dee joined a new formed choir (6)
3.This bore requires strong nerves (7)
4. Warm material (5)
5. Could be a pathway for the sun (6)
Thanks for any help.
I am 99.99% sure that Severn will be correct. The river is famous for its bore and the answer is also an anagram of "nerves". It will be a typo or other error by the compiler and it should say (6) rather than (7). (maybe the compiler was thinking of the answer "severn" sounds like "seven" when he/she typed (7)!)
