How is the inheritance distributed among the heirs: a wife, a son, a daughter, four paternal half-brothers, and a paternal half-sister?

The heirs among those mentioned are only the wife, the son, and the daughter. The brothers are excluded by the presence of a child. The wife receives one-eighth due to the presence of a child, and the remainder goes to the son and daughter by ta'sib (agnatic succession), with the male receiving the share of two females. Estate matters must be referred to the Sharia courts for a precise investigation, as there may be wills, debts, or rights that take precedence over the rights of the heirs.
