Bighorn Sheep: done by Safari LTD, K&M, Wild Republic, New Ray, AAA, Funrise and Tree House Kids. I think the most accurately painted is K&M:

Kiang, Onager/Kulan:
Auburn Rubber made a model in blue, it could be repainted:

Yowies made a model supposed to be Syrian wild ass, but very simplified, it could pass by a badly done domestic horse:

Pronghorn: made by K&M, Mojo Fun, New Ray, Play Spaces and Safari LTD. I think Mojo has the best quality one:

Andean Bear: done by Colorata, K&M, PEC and Play Visions. I think Colorata is the best one and it's the one that I already linked before in this thread.
Asiatic Black Bear: done by Schleich, Colorata, Noah's Pals, Kayiodo, Bandai, Britains Lead, Bullyland, Eikoh, Wild Republic and Safari LTD. Maybe the last brand have the best one:

Aurochs: done by Club Earth, Starlux and Yowies. Not fully satisfactory but I think Starlux have the best one:

Forest Elephant: done by Jean Hoefler and Starlux. The Starlux mode have forward-oriented tusks as in bush elephant so Jean Hoefler is more accurate, despite lack of quality:

Javan Rhinoceros: done by Bullyland and K&M. Both brands do not differ much in quality. Here's the Bullyland one:

Sumatran Rhinoceros (I do have Safari’s) if you have one, then you already saw one! Definitely the Safari LTD model is perfect and accurate, the other brand that did this species is Pfeiffer but much worst quality and lack of accurateness (it's like a Javan (no wool and grey) but with two horns!)
Sambar: done by Bandai.

Axis Deer: done by Bandai.

Smaller monkeys: Many brands did several kinds of tamarins, marmosets and lemurs with different grades of accurateness. I like specially the new Safari LTD toob:

Smaller Canids: Golden and black-backed jackal, red, arctic, kit and bat-eared foxes and tanuki has been made by several brands.
Seals of the world: Literally that, really nicely painted adult pairs of every Earless Seal, Walrus. and Eared Seal species.: Walrus, Australian/Californian/Japanese/Steller's/South American sea lions, Northern, New Zealand and Antarctic fur seals, unspecified sea lion, and bearded/grey/harbour/harp/hooded/leopard/spotted/ringed/Weddell's seals as well as Caribbean and Hawaiian monk seals and unspecified (supposedly Southern) elephant seal has been made. A looot to choose!
Still missing some nice species such as Ross's, Baikal or ribbon, but you will have the nearly complete suborder if you buy them all!
Stellar’s Sea Cow: done by Albert Heijn, Club Earth, Innovative Kids and Yowies. None of them have a good quality, tough. Here is the Club Earth one, maybe the best in shape/sculpture:

Wisent (I have the one Schliech released 15+ years ago, time for another. Ditto their Roe Deer). Appart of the Schleich's one (that is enough good as for don't needing an update), you also have the species made by Albert Heijn, Bullyland, Danolin, Lineol 360, Neo-Form and Starlux. The Lineol 360 one is the best in my opinion, tough is not fabricated anymore since 1960!:

The remaining species/forms that you mentioned seems likely never made into figurine.
