I used no supports, pretty much works except the very bottom of the angel's wings are not quite right. I suggest perhaps custom supports just for those two spots. The models as provided stand about 2 inches tall, and I suspect may be a bit fragile at this size, depending on the details… if material quality or printer accuracy is under suspicion, you'd be wise to scale them up a bit. I did 20% infill on the two in PLA, and a TPU Devil at 15%. The PLA ones are kind of heavy actually (for their size I mean… They were around 26 & 33g respectively), 15% is probably better, or even 10%. I put a standard little loop on top, just add wire, or hook, paperclip or whatever, you'll figure it out :).
