Darren Kelly, 42, from Basildon, Essex, died after he was attacked in the street.
The girl is in custody, police said.
A 20-year-old man, 17-year-old boy and 15-year-old girl, all from Pitsea, and a 16-year-old boy from Basildon have been arrested on suspicion of murder and remain in custody.
A post-mortem examination found Mr Kelly, a lorry driver, was likely to have died from "multiple stab wounds and blood loss", Essex Police said.
His daughter Zoe said she was "heartbroken," adding she and her father were very close and lived a short walk away from each other.
"To know he's not going to be round the corner anymore is very hard," she said.
"I'm sure I can speak for everyone when I say that he's going to be truly missed."
Residents of Caister Drive, where the attack took place, say Mr Kelly rang their doorbells to ask for help after he was stabbed at about 21:30 BST on Tuesday.
Carole Crisp, 56, said: "He managed to get to our block and was just randomly pressing the buzzers for help.
"When I answered he said 'help me I've been stabbed'. I'm just in shock and so sad we couldn't do more."

Parts of Caister Drive are still sealed off, with much of the investigation centred outside two of the street's blocks of flats.
Since I've been here a lorry has been pumping the drains, with police officers and highways engineers working alongside. I saw someone else come along with a shovel to get what they could out of the drains.
Aside from the police presence, the street is relatively quiet with just the odd passer-by or neighbour coming and going, as people here come to terms with what has happened down their road.

Willett, 29, was due to partner Lee Westwood when the 72-hole tournament begins in Melbourne on 24 November.
But the Masters champion does not want to risk aggravating the issue that saw him miss October's British Masters.
"Considering everything, including the amount of travel involved and extra strain, I decided that it was not in my best interests," Willett said.
The four-day competition would have been the fifth tournament in consecutive weeks for Willett, who has dropped out of the world top 10 for the first time since his Masters victory in April.
Willett is second in the Race to Dubai and is tied for 54th in the penultimate tournament, the Nedbank Golf Challenge, after a round of 74 at Sun City.

In March, the Gulf state said that those without papers would not be arrested if they left within 90 days.
The deadline was extended by another month, but so far only 60,000 out of an estimated 400,000 Ethiopians have left, the Ethiopian government says.
Ethiopians make up a large portion of the kingdom's undocumented workers.
All those without papers now face imprisonment or forced deportation.

Ethiopia's Communications Minister Negeri Lencho told the BBC he feared what could now happen to his compatriots who were still in Saudi Arabia, adding they must return "with a sense of urgency".
"They will be imprisoned and we don't want our citizens to face unnecessary imprisonment, or suffer any physical harm or humiliation," Mr Lencho said.
One of those who returned is 28-year-old domestic worker Nura Ahmed. "Life was really tough," she told the BBC's Emmanuel Igunza just after she arrived in the Ethiopian capital, Addis Ababa.
"Sometimes I was jobless because I did not have the proper documentation, so I had no freedom to move around.
"One can never be at peace there," she added.
In 2013, a number of Ethiopians died in clashes with Saudi police as they were being rounded up for deportation.
Saudi Arabia attracts migrant workers from around the world, particularly Africa, and south and south-east Asia.
Saudi authorities estimate that up to one million people are working in the country illegally.
So far, tens of thousands of people of different nationalities have taken advantage of the grace period and have either left or acquired correct papers.
