What is the share of each heir from the aforementioned inheritance?

Those mentioned in the question are considered ذوو الأرحام (relatives by kinship/uterine relations). The preponderant opinion is that they inherit by way of "tanzil" (descent), where each ذوو الأرحام is placed in the position of the heir through whom they are related. Thus, the full sister's daughter inherits the share of the full sister, the full sister's son inherits the share of his mother, and the full brother's daughter inherits the share of the full brother.

Accordingly, if a woman dies and leaves behind a full sister's daughter, two full brother's daughters, and two full sister's sons, and there is no other heir, the distribution of the inheritance would be as follows:

To the first full sister's daughter: one-quarter, because she is in the position of her mother, the full sister. To the two full sister's sons: one-quarter, because they are in the position of a single sister. To the two full brother's daughters: one-half, because they are in the position of a single full brother.
