Yes. See the related question below for more info.
Cows are easily able to lick enough salt from a block to sustain them long term. Horses lack the ability to lick enough salt from a salt block, so most do better with loose salt. However, the ingredient (salt) in a horse salt vs. a cow salt is the same. Mineral blocks and loose mineral is different for cows and horses. Cows and horses have different mineral needs, but their requirement for salt is similar. Yes. Salt blocks are standard for both cows and horses: there really is no discretion as to whether a particular block is better for horses than cows or vice versa.
Yes, yaks do eat salt. Like many herbivores, they require certain minerals to maintain their health, and salt is an essential nutrient for them. In the wild, yaks will often seek out natural salt licks to fulfill their dietary needs. In domesticated settings, salt is typically provided as a mineral supplement to ensure they receive adequate nutrition.

Not all recipes require salt. Some recipes use other spices in place of salt. Many recipes that include salt will turn out fine if you leave the salt out because of a low sodium diet.
Don't bother limiting how much salt a cow needs. She will get as much salt as she wants if you have it left out free-choice. Cows that are salt-deprived tend to eat more salt than those that are not salt-deprived.
Sodium should be fed free-choice as Salt (NaCl), which is found in most commercially made salt blocks or loose salt-mineral mixes.
