To what extent does the عصْبة (agnatic kinship) extend? Does it reach, for example, the paternal cousins of the grandfather?

"Asabah" refers to the male relatives on the father's side, and their categories are five: sonship (bunuwwah), fatherhood (ubuwwah), brotherhood (ukhuwwah), paternal unclehood (umumah), and clientage (wala’). This includes brothers and their sons, paternal uncles and their sons, the paternal uncles of the father and their sons, and the paternal uncles of the grandfather and their sons, no matter how high up the lineage. After these comes clientage (wala’), and there is no limit to how far up or down the lineage they extend.
