If a pilgrim falls asleep at Muzdalifah and misses the Maghrib and Isha prayers (which are combined and shortened there), they should pray them as soon as they wake up, as prayer is not waived due to sleep. The night stay at Muzdalifah is wajib (obligatory) according to the majority, but the Hajj remains valid if missed. A dam may be required for missing the stay according to some scholars.
The night at Muzdalifah is part of the Hajj journey, and the Sunnah is to pray Maghrib and Isha combined and shortened (qasr) upon arrival from Arafat, then rest until shortly before Fajr. If a pilgrim falls asleep and misses the combined Maghrib and Isha prayers, they must pray them as soon as they wake up, because the Prophet (peace be upon him) said: 'Whoever sleeps through a prayer or forgets it, let him pray it when he remembers it, for that is its time.' Prayer is never waived due to sleep or forgetfulness.
Regarding the stay itself at Muzdalifah, the majority of scholars (Hanafi, Maliki, Shafi'i) consider it wajib (obligatory). The Hanbali school considers it a rukn (pillar) of Hajj according to one opinion, though the well-known position is that it is wajib. Sheikh Ibn Baz held that the stay at Muzdalifah is wajib, and missing it without a valid excuse requires a dam (sacrifice). If a pilgrim was present at Muzdalifah even briefly during the night or before Fajr, they have fulfilled the requirement.
Sheikh Ibn Uthaymeen clarified that if a pilgrim arrived at Muzdalifah, fell asleep, and woke up after Fajr having missed the entire nighttime supplication and the Fajr prayer at Muzdalifah, they should pray what they missed immediately. Their Hajj is valid because they were physically present at Muzdalifah. However, they missed the Sunnah of the lengthy supplication after Fajr at Mash'ar al-Haram. The stay itself was fulfilled by their physical presence during the night, even while sleeping.
The Prophet (peace be upon him) said: 'Whoever sleeps through a prayer or forgets it, let him pray it when he remembers it, for that is its time. There is no expiation for it other than that.'

Scholars from different schools of Islamic jurisprudence offer varying perspectives on this matter.
The stay at Muzdalifah is wajib. Missing it requires a dam. Prayers missed due to sleep must be made up immediately. Physical presence at Muzdalifah fulfills the stay requirement even if one slept.
Al-Hidayah: the stay at Muzdalifah is wajib, and missing it requires a penalty.
The Maliki school considers the stay at Muzdalifah wajib. The key requirement is being present at Muzdalifah during the latter part of the night. Sleeping through does not invalidate the presence.
Al-Mudawwanah: Imam Malik considered the night stay at Muzdalifah obligatory.
The stay at Muzdalifah is a Sunnah mu'akkadah in the Shafi'i school, not wajib. Missing it does not require a dam, though it misses significant reward.
Al-Majmu' by al-Nawawi: the stay at Muzdalifah is a confirmed Sunnah, and missing it does not require a penalty.
The Hanbali school holds that the stay at Muzdalifah is wajib (with some scholars considering it a pillar). Being present even briefly fulfills it. Missing it requires a dam.
Al-Mughni by Ibn Qudamah: the stay at Muzdalifah is wajib, and some Hanbali scholars considered it a pillar of Hajj.
