If the 12 apostles existed, it seems unlikely that they'd all be buried in the same place, in what may have been a "prestigious" tomb. Jesus isn't exactly described as a particularly popular figure in his time when it came to the authorities, and I would expect the 12 apostles would have died at different times, in different places, and wouldn't have been buried together.
The time range is pushing it, too: between 400 BCE and 106 CE, though that's just the roughest of estimates based on when the city was founded and when it was annexed by the Romans, not based on any inspection of the remains. It feels more likely that this tomb was built, used, and sealed up well before Jesus and the disciples/apostles supposedly lived.
Even if we assume the religious fairy tales are true, this doesn't pass the smell test: it's vanishingly unlikely that these are the remains of those men, or that any of this is related to the Holy Grail mythology.

It was always a point made from very early times that Rome was the church of Peter. As opposed to places like Alexandria for example whose status came from it being the see of a disciple of Peter.
Something else I seem to recall is that one of the leg bones was different -- what would be expected from a Galilean fisherman always putting one leg on the side of a boat to haul in a fishing net.
The final resting place of a number of Apostles is more or less known -- Ss Simon and Jude are in Saint Peter's, Saint Paul is buried in Saint Paul Outside the Walls in Rome, Saint James the Greater is at Compostella in Spain, Saint Bartholomew is in a church on an island in the Tiber in Rome, Saints Philip and James the Lesser have their own church in Rome I think.
Other Christian circles, and a large swathe of historians, disagree on this front. However, it is one of the founding points of the Petrine Primacy, or the reason that Saint Peter is seen as the First Pope of the Catholic Church.
Christianity is India's third-largest religion with about 26 million adherents, making up 2.3 percent of the population as of the 2011 census.[1] The written records of St Thomas Christians mention that Christianity was introduced to the Indian subcontinent by Thomas the Apostle, who sailed to the Malabar region (present-day Kerala) in 52 AD.
The ending of Indiana Jones and the Last Crusade used Petra as the outside shot for the ancient temple where the story ended.
