No, according to historical accounts, Mark and Luke were not apostles. They were companions of apostles and wrote the Gospel accounts in the New Testament.
The Gospel of Luke was written around the end of the first century CE, or quite early in the second century. The First Roman-Jewish War had come to an end back in 70 CE, and the Romans were once again undisputed rulers of Judea. The Second Roman-Jewish War was still decades away. The Jews had banned Christians from their synagogues, and there was growing animosity between the two groups, as evidenced in the gospel. John's Gospel, which was written somewhat later, shows how this animosity was growing, to the point of real hatred. Luke's Gospel was probably written for a particular community, rather than the entire Christian world. The author appears to have seen a need to demonstrate that Christianity was based on actual history, and probably used historical information from the works of Josephus to provide the historical background previously lacking. The need for a historical background suggests that some were disputing the reliability of Mark's Gospel.
