What is the ruling on one who, due to his ignorance of the rulings of stoning the Jamarat during Hajj, threw a single Jamrah each day on behalf of himself and two women? Is there a compensatory sacrifice (dam) due for this, and how much is it? And is he sinful for delaying it?

Throwing the pebbles (ramy al-jamarat) is one of the duties of Hajj. The large jamarah (Jamrat al-Aqaba) is stoned alone on the Day of Sacrifice (Yawm al-Nahr). On the Days of Tashreeq (11th, 12th, and 13th of Dhu al-Hijjah), all three jamarat are stoned, starting with the small one, then the middle one, and ending with the large one. Each jamarah is stoned with seven pebbles, while pronouncing the takbir (Allahu Akbar) and making supplication after each jamarah, except for the large one. Appointing someone else to stone on one's behalf (tawkeel) is permissible in cases of incapacitation or extreme hardship. Stoning is performed on behalf of a child and on behalf of one who is unable to stone due to illness. As for one who misses the stoning of the jamarat: Al-Shafi'i and Ahmad are of the view that if one misses three pebbles or more, a compensatory sacrifice (dam) is required; anything less than that requires charity (sadaqah). Malik is of the view that a single missed pebble requires a dam, and missing one jamarah or all of them requires a camel (badanah). Abu Hanifah is of the view that missing Jamrat al-Aqaba or all the jamarat requires a dam. The most preponderant opinion is that of the Shafi'is and Hanbalis, which states that a dam is required for each day, or for each jamarah, or for missing three pebbles or more.
