inn
In a manger in Bethelehem, outside of a full inn. The innkepper let them stay in there.
The Bible does not tell us what conversations Joseph had with the people he was looking to stay with when he and Mary arrived in Bethlehem.
I believe she was around 15 or 16 years of age.
Mary and Joseph traveled to Bethlehem for a census. Mary gave birth to Jesus in a stable because there was no room at the inn. They were visited by shepherds and wise men who came to honor the newborn baby.
When traveling to Bethlehem during the census, Mary and Joseph did not stay at an inn, as there was no room for them.(Luke 2:4-7) They stayed in the stable. No name was given for either place in the Bible.
Joseph and Mary were the parents of Jesus of Nazareth.
Nobody. To be more specific, the Bible does not say that Mary and Joseph were told that "all the inns were full." The relevant passage here is Luke 2:7, which says (NIV) ".... She wrapped him in cloths and placed him in a manger, since there was no guest room available for them." Some translations specifically use the word "inn", others don't, but either way how they found out there was no room is not specified, and certainly no particular name is given.
Mary rode on a donkey, and Joseph walked
No, Mary was not married to Joseph when she conceived.
As there was no place in the inn, Mary and Joseph stayed in the manger, but if you are asking where they stayed later, it is in Nazareth.
Joseph and Mary recognized Jesus in the temple.
The question is not clear. Joseph was Mary s husband.
