Lots of goodies once you look outside the Anglophone internet!
La Torre di Cotone started a Nativity Scene in crochet in 2013 and continued in 2014 and 2015. The original set is available here. In the following years the basic shapes were simplified so the people are different but the animals are the same.
It is a bit of a nightmare to navigate, but there are heaps of patterns here. As well as your basic Holy Family, Angel, Shepherds, Wise Men, Ox and Ass (Buey e Asinello), Camels, Sheep, you can also have a butcher, a baker, a fisherman, chickens, flower sellers, pipers and probably lots more!
The Cookie Snob has a cute set of variations on another basic doll pattern for to make people for a Nativity Scene. See her cute little dolls here.
Lalalatoys and DMC banded together to make this nativity set in a beautifully formatted pdf with crochet charts.
Mis Pequi Cosas has 3 kings, shepherd and holy Family amongst her patterns
