The characters first appear in the classic Lion King as young lion cubs who grow up through the story. They both also appear in The Lion King 2 where they are adults who now rule over the lions and have a child of their own. Simba and Nala also appear in the Lion King 1 1/2, which is Timone and Pumba's funny take on what happened in the Lion King.
Simba and Nala apparently first met when they were young cubs when they were growing up in the Pride Lands. In the film, this isn't seen, as they are already close friends by the time we first see Nala.
In the 2019 live-action remake of "The Lion King," the roles of young Nala and Simba are voiced by Shahadi Wright Joseph and JD McCrary, respectively. These talented young actors provide the voices for the characters during their younger years in the film.
The only lionesse's names thet are officially known as in confirmed by the film makers. are Sarabi, Sarafina and Nala. Sarabi is Mufasa's mate and Simba's mother. Sarafina is Sarabi's friend and Nala's mother and Nala is Simba's friend.

There are more than two lions in The Lion King so whichever two do you mean is unclear, so to answer the question, here are all the official lion characters from the official The Lion King which is the movie universe only. The names and who they are in the films:The Lion King: Simba (the prince), Nala(Simba's best friend and future queen), Mufasa and Sarabi (Simba's parents as in the king and the queen), Sarafina (Nala's mother, Nala's father is officially unknown), Scar (Simba's uncle and Mufasa's brother.)The Lion King 2: Simba's Pride: New characters are: Kiara is Simba and Nala's daughter and their first and only child. Zira is a grown up female lion whose official origin besides that she belonged to Scar's pride, is unknown, but there are several fan theories. Kovu is Zira's youngest child and the last born before Simba exiled them after returning and killing Scar. The film states twice that Scar was not Kovu's father. Nuka is Kovu's older brother. Vitani is Kovu's older sister and Nuka's little sister.There are many profit fanfiction books and comics that introduce numerous new lion characters but none of them exist in the official movie universe.
The main character was Simba, the son and prince of Sarabi, his mother, and Mufasa, his father, and the King of Pride Rock where they all lived. There was Zazu, the messanger bird for the King, Nala, Simba's female best friend, Scar, Simba's Uncle who wanted to be King in place of his brother, Mufasa, the three hyena's, Nala's mother, Sarafina, Timon and Pumbaa, a warthog and a Meercat that meet Simba later in the movie, and Rafiki, a babboon who is like the witch doctor.
The Lion King directors Roger Allers and Rob Minkoff stated during a Lion King 10th Anniversary Reunion that it could be either Mufasa or Scar. Despite this "canon" claim, Nala would be related to Simba and Scar nor Mufasa acknowledge Nala as their daughter in the film so the mystery of who is Nala's father is left up to fanfiction.
The hyenas killed Scar as the film shows a shadow of the hyenas leaping upon Scar trying to devour him.
Nala helped during the film by trying to convince Simba to take his place as king. Although, it didn't work, but it did lead Simba to seeing his father's spirit which really convinces him to take his rightful place. She also helps by fighting off the hyenas during the climatic battle towards the end of the film.
Her name is Sarafina, who was seen for a short time when Nala was having a bath, when Simba was asking her to come to the elephant graveyard. Sarafina had a line in the second film commenting on Kiara: "My, how you've grown!"
The Lion King directors Roger Allers and Rob Minkoff stated during a Lion King 10th Anniversary Reunion discussion panel that it could be either Mufasa or Scar. Despite this "canon" claim, Simba and Nala would be related, and neither Mufasa or Scar acknowledge Nala as their daughter so you can accept what the directors said or just leave it to fanfiction.
