Bill, I have seen many keys used for most of the songs. The exception is The Christmas Song which seems to always be in Eb. Several Christmas songs are almost always in the key of D but none of those you listed. This is the list as I use it:

Christmas Song – Eb
Silent Night – C
Rudolph – C
Away In Manger – G
White Christmas – C
Jingle Bells – G
Deck The Halls – F
God Rest Ye – G
Good King W – G
Winter Wonderland – F
Sleigh Ride – G
Have Yourself A Merry - C
