Hello Rahul009 

Use a common local variable to save the response form both the interfaces, which would save a value that would decide which interface to display. 

example have a rule input in the 2nd interface which would save a value on the dynamic link of the cross icon. use the local variable from the parent/interface1 as the value in this interface2 rule when called in the interface1

a!localVariables(
  local!showWhen:false,
  {
    if(
      local!showWhen,
      rule!KS_xyzqwe(showWhen: local!showWhen)/*Your Interface 2*/,
      a!richTextDisplayField(
        value: a!richTextItem(
          text: "Show interface 2",
          link: a!dynamicLink(
            saveInto: a!save(local!showWhen,true)
          )
        )
      )
    )
  }
)

in the rule for the child interface the icons dynamic link save a Boolean value into the rule input.
