Eevee from Pokemon has several varieties that could match:
Espeon matches your description of a reddish gem in the forehead, while Umbreon better fits the color of the figurine (and has red eyes). The ear shape fits Espeon better, it would seem, although who knows how accurate they're being about such things. Each has diagonally-oriented eyes, though, rather than the horizontally-oriented eyes of that statue.
It could also be a stylized, somewhat cartoony version of an Egyptian black cat, many of which are portrayed with a third eye or a scarab on their forehead. It's somewhat hard to tell, but this brightened GIF seems to show a golden necklace hanging just below the figure's neck:
To my eye, it seems to be a generic cat figurine which resembles several things, rather than being an actual representation of some specific character. The other toys seem similarly generic, and it's worth noting that Yondu seeks them out for their kitschy, aesthetic quality, not because he's a fan of any particular franchise, so they don't necessarily represent anything at all.
