Fragile - tenuous: Whatever they were in the mountains, they could be no more. However tenuous their well-being, however much they had suffered and would suffer again, they had found a way out of the wilderness.

Lobby - beg and barter: In order to consummate the ancient sacrifice—to impale the head of a buffalo bull upon the medicine tree—a delegation of old men journeyed into Texas, there to beg and barter for an animal from the Goodnight herd.
The verb lobby means to persuade. In this passage the old men are trying to persuade someone for an animal.

Antagonist - Enmities: Some of them painted their faces and carried the scars of old and cherished enmities.
Enmities is another word for something that is hated, just like an enemy. An antagonist goes against a person or thing and is often hated or strongly disliked so this would be the best choice.
