What is the ruling when three sons exist, and one son admits to having an additional brother and sister, and one of the other brothers affirms the existence of the brother but denies the sister, while the third brother affirms the sister but denies the brother?

The lineage of the affirmed brother and sister is not established in this scenario. The acknowledging son must give both the alleged brother and sister one-third of what is in his possession. Specifically, the portion given to the alleged brother is one-quarter of the acknowledging son's possession, and the portion given to the alleged sister is one-seventh of the acknowledging son's possession. The detailed calculation involves determining the common denominator for the proportions derived from the initial share division, resulting in an allocation of 168 shares to the one acknowledged by both, 216 shares to the one acknowledging the sister, 189 shares to the one acknowledging the brother, 119 shares to the confirmed brother, and 64 shares to the confirmed sister, out of a total of 756 shares.

There is no difference in the ruling whether the two remaining brothers affirm or deny the claims, as neither one possesses more than their rightful inheritance share.
