1) Relationships can be configured to be 1:1, 1:M, or M:N. The cardinality of associations is determined by the feature restrictions of the utility network.

2) By default, associations are M:N. However, point features are only allowed to have a single container.

You can learn more about how associations behave by reading the feature restrictions page I linked to above, or by referring to the specific pages for connectivity, containment, and attachment.
