What House or placement in our charts would show what types of people we are attracted to as friends?

For friends, look to the house Aquarius is in, Ur, and the ruler of the natal 11th. When you speak of platonic, it relates to the 7th and not the 11th. And thant includes any relationship, partnership, common law, etc... All relates to the 7th. When you talk about platonic relationship, you would have Aquarius on the 7th cusp or Ur.
