Icchini Panwar (with her sword), Daughter of Salakha Rai
Icchini was Parmar Princess of Mount Abu. According to Prithviraja Raso, she was daughter of Salakha Rai and her sister Mandodari was married to Bhola Bhim. However, Bhimdev fell in love with Icchini and threatened Salakha to surrender her to him or face grave consequences. Her brother Jaitsi refused this marriage offer and married Icchini off to Prithviraja Chauhan as per previous plan. Bhimdev got angry and attacked Abu and in it her whole family died which later led to many skirmishes between Prithviraj and Bhimdev. History suggests Prithviraj wasn't successful in his campaign against Chalukyas unlike what Raso says.
Icchini became his Chief Queen and was mother of his sons (the number is not mentioned in Raso). Pritha, Prithviraj’s sister preferred to stay in her palace whenever she visited from Chittor.
Icchini Panwar as a warrior
It's alleged that she was mother of Govindraja as well. She was a warrior princess and it's alleged that when she got to know her husband was captured, she went in the battlefield to rescue him but got martyred.
Icchini had the title of Patrani and Kanha Chauhan called her Gauri for Shiv like Prithviraj. She was his second wife by chronology but held the highest place among all his queens.
Daughter of Nahar Rai Parihar, King of Mandowar
The princess of Mandowar who was daughter of Raja Nahar Rai was the first wife of Prithviraja Chauhan. He was of tender age of eleven years old when he (most likely his warriors) fought against Nahar Rai because he backed off from his promise to marry off his daughter to Prithviraj and called Chauhan clan not equal to Parihar (Pratihar). This angered Prithviraj and when Nahar Rai was defeated, he accepted Vassalage of Ajmer and married off his daughter to Prithviraj Chauhan.
Pundhirni
The daughter of Chandra Pundhir was very beautiful and Prithviraj fell in love with her beauty. He proposed marriage to her father and he gladly agreed for the alliance. Pundhirni and Prithviraj got married with no obstacles in their marriage.
Dahimi
The daughter of Dahim Rai and sister of Chamund Rai Dahima was another wife of Prithviraja Chauhan. Some versions of Raso calls Pundhirni and Dahimi as one woman.
Dahimi was mother of Kunwar Rainsi who was made Crown Prince of Delhi by advice of Rawal Samar Singh (brother in law of Prithviraja Chauhan in Raso) and other Samantas. Rainsi died fighting against Ghurids after he tried to take revenge of the brutal death of his father. His family did Jauhar.
Padmavati
The princess of Samudrashikhar Garh and daughter of Kunwar Padmasena fell in love with Prithviraj Chauhan but she was promised to Raja Kumodmani of Kumaon. She sent a letter to Prithviraja Chauhan and he came to take her. He took her from a temple where she went to pray and Prithviraj took her. The army went after them but Prithviraj defeated them. The story of sending letter to Prithviraja comes in Padmavati’s story not Sanyogita.
Shashivrata
Shashivrata was princess of Yadavas of Devagiri and she fell in love with Prithviraj Chauhan and vice versa when a dancer went to the palace of Prithviraja and described him the beauty of Shashivrata. He came to Devagiri and took Shashivrata away from the temple of Lord Shiva as she wished. Her fiance (Virchandra or Jaichanda or Kamdhwaj, the story has discrepancy of who exactly was her fiance) and her army fought Prithviraj but they escaped successfully.
Indravati
Daughter of Bhim Parmar of Ujjain was betrothed to Prithviraja Chauhan but he went to help his brother in law in a war and sent Panjjun Rai with his sword to get married to Prithviraj's sword. At first her father felt insulted and rejected the alliance but after skirmishes and the king understanding it would bring no good to him, Indravati was married to Prithviraj's sword and she became wife of Prithviraja Chauhan.
Princess of Kangra
Prithviraj had fought with Kingdom of Kangra with its ruler, Raja Bhan Bhoti. After he defeated him, the Raja married off his beautiful daughter to Prithviraj Chauhan.
Hansavati
Hansavati was princess of Ranthambore and daughter of Raja Bhanu Rai. Panchaeen, King of Chanderi wanted to marry her because he fell in love with her but her father wanted a better match for her. Panchaneen attacked him and he called Prithviraj for help. Prithviraj along with his brother in law Samar Singh came to his aid and defeated Panchaeen. The King became really happy and he married off Hansavati to Prithviraja.
After Hariraj defeated Govindraja (allegedly his mother was Icchini Panwar), he fled to Ranthambore and established separate line of Chauhan rulers in the region.
Sanyogita
Daughter of Jaichand and Princess of Kannauj named Sanyogita was the last wife of Prithviraja Chauhan. She fell in love with him and eloped with him from her palace near Ganges river where she was on House arrest because she refused to do her Swayamvar and garlanded the statue of Prithviraj. He became obsessed with her due to which his main queen Icchini almost left him and only stayed because he begged her. Sanyogita was his most favourite and like an obsession. Chandra Bardai criticized the relationship and Samar Singh told Pritha that the way Prithviraj was behaving, it would lead to Ghurids capturing Delhi. Gururam said she was the cause of destruction of Prithviraj and death of his most capable officers.
When she heard Prithviraj was captured, she died instantly and Pritha led the Jauhar with other queens.
Source- Prithviraja Raso (Largest version), Raso is an interpolated source
There are mention of other wives like Kurambhi, Bangujjari etc. It's mentioned that Icchini was above every queen but when Sanyogita came he spent day and night with her and this led to massive jealousy in every queen.
Sanyogita was very respectful to all his queens and even gave them a grand feast. Icchini faked friendship with Sanyogita to get to know about the love life of her with Prithviraj.
The queens had jealousy with each other but due to the constant threat of Ghurids, they didn't have time to do any kitchen politics so the queens mostly stayed united because they were constantly under pressure to save their honour.
Dahimi’s son Rainsi was the Crown Prince but no queen objected it because the danger looming above them was so great, they needed to stay united at that time.
Prithviraj might have had married for political alliances and all these love stories and calling him to get them looks like poetic creative liberty. Prithviraj didn't have time for love life because since his childhood, he was busy in wars. Prithviraj was busy in capturing Tabarhind after first Battle of Tarain so it's highly unlikely he would attack Kannauj that too to get a princess. It's very unrealistic and does not go with the personality of Prithviraj Chauhan. Chronology of Raso also doesn't match with history as it makes Bhimdev and Samar Singh as contemporary of Prithviraj Chauhan.
