They are all family III Smile figures. There are 3 different Smile coos and one of them, the 1c, not listed on Wolff’s guide, often comes with light limbs which can be mistaken for the light poch paint.
There is actually a debate as to whether there is a PBP yoda with most people thinking PBP packed the Lili Ledy Regresso yoda on PBP cards.
There is an POCH Greyhead Yoda with a family I Kader CoO and a POCH Apple with family II Unitoy CoO. But both of these are quite distinctive.
There are some POCH hybrid combos with a combination of Unitoy and Kader bodies, heads and limbs but again the paint on the limbs is key.
Hope this helps.
