"Is this at least/most CR 1"

TL:DR Belowest

Background

Spoiler

So today me and some friends got turned into animal experiments, or at least, our characters did, but the DM let us decide what kind of experiment. (Which explains why they didn't ask us to make a character sheet, which I thought was odd, anyways) so we set to work on our respective tasks, the one limitation was "it can't be beyond CR 1, which killed the Dragon Lich hybrid idea two members were planning. So we ended up with a Sneagle (Snake Eagle, named Coatl Jr.) A Badger Turtle, a Raccoon Wolf (1/2+1 = .75 I guess) a Weasel Vulture (Scariest Griffin EVER) and my monster, I mean creature, A Spider Monkey (There was a Point to all of this) All I'm wondering is if this
a) Comes close to being CR 1, and if over how much
b) Comes close to the other members.
