Everyone vs. Every One

1
Everyone vs. Every One

• Everyone is referring to all the people in a
  certain place, while Every One means the specific
  individuals making up a group. Like if I say
  everyone put your hand in! then you would all
  put your hands together in a dog pile fashion.
  But if I say every one of you but Kayla and I
  have their hands in a pile then it would just
  apply to the people involved in the action.

2
Of vs. Have

• Of is a preposition while Have is a helping verb.
  Think about being able to have a piece of candy,
  you can actually hold it and its in your
  possession. You cant of something, you can have
  a piece OF candy
