I'm fairly certain Stevie is in Warm Ways. She is certainly on Everywhere--you can hear her, and Mick makes a point of discussing her participation on it in his book.

Stevie does not sing on the album version of World Turning.

No idea about Only Over You--Stevie probably isn't on it. She may be on Wish You Were Here, but again, I doubt it. She is, I believe, absent from Hold Me.

Christine is vocally absent on I Don't Wanna' Know. She may be playing a mixed-down organ part on it, but I can't hear it. Stevie does not sing on Don't Stop--but some studio hands sang along to the last part of the song--according to Ken Caillat.
