I dont know of any active Imps. There are 4 active Cait Sith and 2 active Spriggans. 1 Active Sylph, 1 active Undine, and 1 active leprechaun (Soon to be two)

^Just as far as I know. No clue about Salamander. 

There's also a severe lack of gnomes and pooka. But yeah, Spriggans rule-

Did somebody say Spriggans?
