Unclued
25 is an abbrev. for Strong, followed by an abbrev. for Earl, then a word (containing the extra I) meaning "suffering from" the whole giving a curse (not a particularly strong one).
24 is a scottish word for do (containing the extra A) followed by a sign of the zodiac giving an affectionate greeting.
2 is a "seat on a jumbo" with the extra O and then replace an abbrev. for a certain sort lord with an abbrev. for a bishop. The whole meaning a common cheer.
Let me know if you want more detail.
I could do with some help with 39.
Thanks
