Mohammed Hashim Ijazuddin, known as Hashim, and Saqib Hussain were travelling on the A46 in Leicestershire when they were caught up in a fatal crash.
Their silver Skoda Fabia left the carriageway and smashed through a central reservation at around 1.30am on Friday.
Two other cars, a grey Audi TT and a blue Seat Leon, were spotted nearby, Leicester Magistrates Court heard today.
All of the vehicles were travelling at speed and one of them was said to have burst into flames.
Hashim and Saqib were pronounced dead at the scene following the crash, Leicestershire Police said.
TikTok influencer Mahek Bukhari, 22, and her mum Ansreen Bukhari, 45, from Stoke-on-Trent, have been charged with murder over the crash.
Natasha Akhtar, 21, from Birmingham has also been charged with murder, as well as Raees Jamal, 21, and Rekan Karwan, 28, from Leicester.
The mother and daughter appeared in the dock at Leicester Magistrates Court this morning, though Akhtar opted to stay in the cells. The men charged are due to appear at Leicester Magistrates Court tomorrow.
Mahek Bukhari has more than 120,000 followers on TikTok and another 43,00 on Instagram, where she poses in a variety of outfits and shares make-up tutorials.
She has racked up 3.2 million likes, and a further 3,750 followers on YouTube where she documents her travels and make-up tips under the name May B Vlogs.
She described her mum as being a best friend, sister and mother all rolled into one.
Ansreen Bukhari is the managing director of a security firm called City Security Plus based in Stoke-on-Trent.
All three charged women will appear at Leicester Crown Court for a bail hearing tomorrow.
The court was told that just before the crash one of the victims called 999. A loud scream was heard before the call disconnected.
Leicestershire Police discovered that two other cars were reported to have been travelling in the area at the time of the crash – a grey Audi TT and a blue Seat Leon.
A 20-year-old man who was arrested on suspicion of murder on Friday has since been released from police custody. He is to face no further police action, the force added.
Detective Chief Inspector Tony Yarwood said: ‘Anyone who was travelling in the area in the early hours and has any dashcam footage, we are urging you to come forward.
‘We are working to piece together the movements of all the cars involved and any footage of them will help our investigation.’
