The IUCN Redlist is the best site to check out.
There are several different lists of endangered species. It depends on which you choose to use. Varying from a few to many hundreds.
white foxes are not a species. If you mean the Arctic fox, no, it is not an endangered species. Wikipedia lists it as "Least Concern".

Yes, they are listed on the major endangered species lists, but not under the specific status of Endangered yet. They are currently listed on the US Fish and Wildlife Service endangered list as a "Threatened" species, and on the IUCN Red list as "Vulnerable," which is a subcategory of the IUCN Threatened status. If their numbers keep growing, and our understanding of them increases, they may be removed from the lists of animals in danger. When animal species are "removed from the lists", they are put under a status of "delisted". Their population has been improving, and they currently number over 20K in the wild, and could be over 25K. See the related questions below for more information about Endangered Species lists and the status categories they use.

A critically endangered species is a species that is in immediate risk of extinction. Currently there are 1821 plants and 2129 animals in this endangered category. The list of wildlife that is critically endangered is so extensive that it would take hours to list every species. The IUCN website lists all endangered species and is a great tool for understanding the threat of extinction and the impact it will have on our world.
The yellow billed cuckoo is not an endangered species. The IUCN lists this bird as least concern.
The population trend for spider monkeys is decreasing. The IUCN Red List lists one species as vulnerable, four species as endangered and two species as critically endangered. Note:There are a total of 7 species of spider monkeys.
