Does anyone know (or is it possible) if a contact is associated with an activity, event, opportunity an error message will appear telling users to update contact?

Actiivities will be tough (nearly impossible) to do with a Validation Rule because the standard Related To: (WhoID) field can't get any deeped into the Contact/Lead object than the ID, so it can't get to the Email field to evaluate if it is blank.
For other objects and especially custom Lookup(Contact) fields you could build a VR that evaluates the Contact.Email and other fields.
