In Matthew's Gospel, Jesus was taken to Egypt out of fear of King Herod. During the several years they remained there it was not possible to take Jesus to Jerusalem because of the continuing danger. After the death of Herod, the family began the return jouney to their home in Bethlehem but Joseph was warned in a dream that Herod's son and successor, Archelaus, would be a further danger, so they turned aside and travelled to the relative safety of Galilee and settled in a city called Nazareth (Matthew 2:22-23). During the ten year reign of Archelaus, the family would not have gone to Jerusalem. In this story, Jesus must have been at least in his teens before he first went to Jerusalem.
Luke 2:41 says "Every year Jesus' parents went to Jerusalem for the Festival of the Passover". The next verse specifically mentions that Jesus went with them when he was twelve (though it's likely he did all the other years too).
Jesus possibly could have been 8 days old because the law stated that a male child was to be circumcised 8 days after birth. But possibly Joseph circumcised Jesus as this was common also instead of having a priest do it.
We are told in Luke 2:22 that when the days of Mary's purification was due, and again the law stated that a women 40 days after giving birth to a son had to go to the priest and be purified, that they, Joseph and Mary brought Jesus to the temple to present Him (Jesus) to the Lord. The dedication of Jesus or any son was also written in the Law of Moses (vs.23; cf Exodus 13:2, 12-15).
So Jesus could have been 40 days old.

The story of Mary, Joseph and Jesus fleeing to Egypt occurs in Matthew's Gospel. We are not told how old he was, but the visit of the magi suggests he was new-born. Some say he was two years old, because King Herod ordered all the baby boys in Bethlehem under two years old to be killed. However, Herod would have given his orders to ensure that, no matter what, Jesus would be killed - so it should be safe to assume that Jesus was much younger than this. At most, we could say he was no more than a few months old.
Luke's Gospel does not have this story, and makes no allowance for it. In this gospel, the young family peacefully travels to Jerusalem and then returns home to Nazareth, which was at that time still in Herod's kingdom. The irreconcilable nature of the two accounts is explained by John Shelby Spong (Born of a Woman: A Bishop Rethinks the Birth of Jesus), who says neither of the nativity stories contains any historical truth.

The Passover.
I believe they travelled to Jerusalem to pay taxes and celebrate Passover while there. After leaving they finally noticed that Jesus was not with them. Frantic, they returned and found the 12 year old Jesus speaking in the temple.

John records Jesus' visits to Jerusalem, particularly at the times of the Passover feasts.
Joseph and Mary brought Jesus to the temple as an infant "after the custom of the law" (to dedicate Him to the Lord), and Jesus was found in the temple "sitting in the midst of the teachers, both listening to them and asking them questions" when He was twelve years old, when the family had gone to Jerusalem for the Passover. Both of these instances are recorded in Luke chapter 2.
Simon of Cyrene happened to be in Jerusalem at the time of the crucifixion of Jesus. It is not explicitly stated why he was there, but it was likely due to his religious pilgrimage for the Jewish festival of Passover. It was a common practice for Jews to travel to Jerusalem during this time.
Mary and Joseph thought Jesus was with their friends.
