Please tell me chronological timeline (in Manvantara and Mahayuga) of Lord Vishnu's various incarnations.
Chapter 47 of Matsya Purana, Chapter 36 Part 2 of Vayu Purana, Chapter 19 of Prabhasa Khanda of Skanda Purana and Chapter 73 Upodgatapada of Brahmanda Purana mention timeline of Lord's some Avataras in Chronological order. These four Puranas mention same timeline. I will also mention from Bhagavata Purana.
In Sweta Varaha Kalpa (current Kalpa)
At beginning of Varaha Kalpa - Varaha Avatara. (Srimad Bhagavatam 3.13)

These are the Lila avatars (I missed few). Then there are also Manvantara avatars too for each of the Manvantaras (LB 4).
The Destroyer has a great answer. However, Puranas when they give dates it can become confusing to separate the Manvantara aspect. Thanks to Srila Rupa Goswami and Srila Baladeva Vidyabhusana, we have Laghu Bhagavatmrta. Below are the lists from various Puranas

Please note that Lord Vishnu's incarnations are repetitive. So you may find more than one timeline for each incarnation. To understand this, let's read the below lines:
However there are very few sources but we can't ignore the story of Kakabhushundi. Kakabhushundi has seen Ramayana 11 times with different outcomes and seen Mahabharat 16 times with different results, but, after seeing Daksha Yagya twice, he did not either care to see it again or saw no point to seeing any more, as it ended the same way each time.
Also, few people believe in this as well:
Vasuki smiled and said, "This world we live in goes through cycles of life and death. In Treta Yuga, Ram takes birth. Then one day his ring falls into the subterranean realm of serpents through a tunnel. A monkey follows it and Ram on earth dies. So it has been for hundreds of thousands of times. All these rings testify to that fact.”
The order of these incarnation is as below, this can be related with modern day evolution theory as well. However, Mohini Incarnation (happened soon after Kurma incarnation during Samundra-Manthan) is an exception where modern day evolution theory fails :
In Sat Yuga : Varaha, Koorma, Matsya (Creatures that live in water/amphibian or live on land with swimming ability)
In Sat Yuga : Nrisimha (The half-lion and half-human – a stage between Homo sapiens and animals; killed Hirnyakashyap)
In Treta Yuga : Vamana (The Homo sapiens with short stature; sent Bali (great grandson of Hirnyakashyap) to Rasatal)
In Treta Yuga : Parasurama (The rough and tough human - Rama with the axe; killed Kartvirya Arjun (the king of Maheshmati) and then his army/descendants many time)
In Treta Yuga : Rama (Rama with a bow & noble practices; killed Ravana)
In Dwapara Yuga : Krishna (no explanation needed!)
Few timelines are as below but it doesn't mean there are no other timelines for these incarnations:
In the very beginning of Svet-Vrah kalp (present kalp) i.e. 1st Sat yuga of 1st Manvantar (ruled by Swayambhu Manu). Lord Varah restored the Earth in the beginning of this kalps, hence, the present kalp is named after Vishnu's this incarnation.
Note: this incarnation happened again to kill the asura Hirnaksh (brother of Hirnakashyap).
Koorma and Mohini Incarnation
Lord Vishnu took these incarnation during Samundra-Manthan (not sure about yuga but most of the sources says that Samundra-Manthan happened in previous manvantra i.e in the 6th or Chakshusha Manvantar of the Svet-Vrah or present kalp).
Note: Lord Vishnu took Mohini form again and Aiyappa was born.
At the end of 6th Manvantar (Cākṣuṣa-manvantara) or in the beginning (1st Sata yuga) of 7th Manvantar (Vaivaswata or present Manvantar) of the Svet-Vrah or present kalp. This incarnation of Vishnu saved Satayvrata from the deluge (Pralaya), who later became 7th Manu (Vaivaswata) and the current Manvantar is named after his name.
Note: This incarnation happened earlier as well to save Vedas from the demon Hayagrīva at the beginning of this Kalpa or at the end of previous Kalpa.
Parasurama and Rama Incarnation
In the Treta yugas of 7th Manvantar (Vaivaswata or present Manvantar) of the Svet-Vrah or present kalp.
Krishna, Krishńa Dwaipáyana and Balrama Incarnation
In the 28th Dwápara yuga which is recently passed (Dwápara yuga in which Krishńa Dwaipáyana holds the title of Ved Vyash) of 7th Manvantar (Vaivaswata or present Manvantar) of the Svet-Vrah or present kalp.
Note: Same is the time line for Krishńa Dwaipáyana (who is know as Vedvyasa, not considered in Dashavataram but in 24 incarnations) and Balrama(few people believe Balrama as Vishnu's incarnation and few as SheshNaga's incarnation).
In the 28th Kaliyuga yuga which is going on (around 500 BCE) of 7th Manvantar (Vaivaswata or present Manvantar) of the Svet-Vrah or present kalp.
Yet to happen in 28th Kaliyuga.
As per Vishnu Purana - Part 3 - Chapter 1, below are Lord Vishnu's avtars in past Manvantara:
Yajna was born in the Swáyambhuva or First Manwantara Ajita was born in the Swárochisha or Second Manwantara Satya was born in the Auttami or Third Manwantara Hari was born in the Támasa or Fourth Manwantara Mánasa was born in the Raivata or Fifth Manwantara Vaikuntha was born in the Chákshusha or Sixth Manwantara
As far as I know Shri Vishnu's incarnation of Varah Avtaar took place at the beginning of this Kalpa. He fought against and killed the demon Hiranyaaksh and restored the Earth along with the 4 Vedas which had been stolen by the demon Haygriv during the night of Bramhdev.
He took out the Earth, which is said to have been drowned at the bottom of the sea due to the Maha Pralay of the previous Kalpa.
So I believe Varah happened only once. No avtaar was repeated as far as I know.
