The other ones I'm stuck on are:
1. Seasonal fruit? (6, 9, 6)
2. 23rd? 02/18. Wear your thermals (6, 7, 5)
I'd guess this is related to the date in some way, but can't figure how.
3. That's risky! (7, 2, 4, 3)
4. Aromatic oil (11)
All I can think of is frankincense, but it doesn't fit the clue length
5. Sing in exultation (6, 2, 6)
I know it's a line from O Come, All Ye Faithful, but can't see anything else in the song that fits the clue length.
