Is anyone able to help us with specific and or published height guidelines for Annie, Molly and Kate ?
Every director makes their own height requirements. Most productions try and keep all of the orphans under 5' tall, though. It also depends on what kind of production of "Annie" it is - a National Tour or Broadway production will probably stay under 5' tall for all of the orphans, because that means the kids can stay in the roles longer. For community productions and non-professional productions, orphans can be as short or tall as the director decides.
