The symbols represented their loyalty to a particular house or Manor. The crest was often used as symbols. Some were family crests or the Kings crest.

Yes. Knights had swords. Also they hadarrows, shields, chain mail and armor.
Earlier knights wore chain mail. Later knights started using plate armour and shields.
Knight Templar shields were typically round or kite-shaped shields made of wood and covered with leather. They were often emblazoned with the iconic red cross symbol that represented the Knights Templar order. These shields were an important part of a knight's armor, providing protection in battle and displaying their allegiance to the order.
omg very important you should know that!
Only in movies do knights carry decorated shields. The shields I have seen in various museums have no decorations. They were to block a blow and not to look pretty.
The shields of Arthur's knights were hanging on a tree in Turquines's land as a warning to other knights that they would meet the same fate if they entered his territory. It was meant to intimidate and deter any potential challengers or intruders.
My guess is that the symbols were family crests.
