Exactly how many people did Lord Krishna marry? How many children did he have?

              Details of the wives of Lord Krishna are given in the "Tenth Skanda of Srimadbhagavata Mahapurana". I am trying to give a brief description from there.

Lord Krishna had '8' chief wives, who were called 'Ashtavarya'.

1 / Rukmini

            Rukmini was the first wife of Lord Krishna and the daughter of 'Vidarbharaj Bhismak'. Rukmini's elder brother Rukmi arranged her marriage with 'Shishupal', but Rukmini wanted to accept Lord Krishna as her husband. For this reason he secretly sent a letter to Lord Krishna to take him away. Lord Krishna defeated 'Rukmi' and took away Rukmini.

2 / Satyabhama

                 Satyabhama's father 'Satrajit' was the richest man in Dwarka. He had the divine 'Samantak Mani' as a gift from the 'Sun God' which produced '20 manas' of gold every day. But Satrajit suspects that Lord Krishna may want to steal the money. On this suspicion he gave the money to his brother 'Prosenjit'. Prosenjit went hunting in the forest with that money and was killed by a lion. As a result, Satrajita accused Lord Krishna of murder and theft. Lord Krishna then brought him the money.

After receiving the money, Satrajit repented and "donated his daughter along with Samantak Mani to Lord Krishna".

3 / Jambavati

             Jambavati was the daughter of 'Jambavan'. When 'Lord Sri Ramchandra' finishes the leela, he says to Zamban, "You will be on earth till the end of Dwapar Yuga and at the end of Dwapar Yuga I will come in the form of Basudev and set you free".

When Lord Krishna was looking for 'Samantak Moni', he met Jambavan and he released Jambavan and married his daughter Jambavati at Jambavan's request.

4 / Kalindi

               No man wanted to marry her because the 'Sun' goddess's daughter 'Jamuna' was Krishna Varna. Then Jamuna promises, "He will get the best of all men as a husband." For this purpose she performed austerities for Lord Vishnu and as a result of her austerities Lord Krishna took her as his wife. This goddess Jamunai is 'Kalindi'.

5 / Mitrabrinda

Mitrabrinda was the daughter of 'King Joysen'. The two elders of the Allies, 'Binda and Anubinda', considered Lord Krishna to be their enemy. After defeating all her brothers in the swayamvara of the allies, Lord Krishna married her.

6 / Satya

According to the condition of Koshalraj 'Nagnajit', "Lord Krishna was able to remove his seven bulls from their place with one finger". Pleased with this, Nagnajit married his daughter Satya to Krishna.

7 / Bhadra

             Bhadra, the daughter of 'King Drishtaketu', performed severe austerities in order to get 'Lord Vishnu' as her husband in her previous birth. For this reason she got married to Lord Krishna. According to some, this was "Bhadra was Surpanakha in pre-birth".

8 / Lakshmana

               Like Draupadi's Swayamvara, Lakshna's Swayamvara also had a strange competition for Lakshabha. After winning this competition, Lord Krishna married Lakshmana.

In this way he received the Ashtavarya.

              Then one day 'Devaraja Indra' came to Dwarka in fear of 'Narkasur' and prayed for help. Lord Krishna heard his prayer and went to fight with 'Satyabhama' and 'Garuda' and killed Narkasur.

             Narkasur kidnapped '18100' womens . Lord Krishna set them free. But to get his release, he went to sacrifice his life. Lord Krishna said to them, "You are free now, but why are you going to commit a great sin like suicide?" In reply, they said, "Society never accepts a wife who has been kidnapped by another man. Now they have no identity and no place in society." So suicide is their only way. Lord Krishna told them, "But I will accept you as my wife. But remember this marriage is only for your social respect. You should never expect anything more than that."

                Thus Lord Krishna had a total of '16106' wives. However, he only gave social identity to the 18,100 girls abducted by Narkasur. But in reality he had 6 wives.

Each of these eight brothers had "ten sons and one daughter, that is, 80 sons and 10 daughters." The list of their names is given below.
