Is it permissible for us to sacrifice a jointly inherited animal (a ram and a ewe) left by our deceased father, after giving one of his wives her share, knowing that only a ram and a ewe remain?

Participation in a sacrificial animal (udhiyah) is permissible for seven people in the case of a camel or a cow, whether they are from the same household or separate, based on what Muslim narrated from Jabir (may Allah be pleased with him): "We slaughtered with the Messenger of Allah (peace be upon him) in the year of Al-Hudaybiyah, a camel for seven and a cow for seven." As for a sheep, it suffices for only one person, with the exception that a man may include his household with him in the reward.
