How does the first noble truth associate dukkha with each of the five skandhas? I'm looking at this definition of dukkha:


  
  Birth is dukkha, aging is dukkha, death is dukkha;
  sorrow, lamentation, pain, grief, &amp; despair are dukkha;
  association with the unbeloved is dukkha;
  separation from the loved is dukkha;
  not getting what is wanted is dukkha.
  
  
  In short, the five clinging-aggregates are dukkha.


Taking this definition of the five skandhas,


The first of the above (birth aging and death) might I suppose relate to "form":


  "form" or "matter"[e] (Skt., Pāli रूप rūpa; Tib. gzugs): external and internal matter. Externally, rupa is the physical world. Internally, rupa includes the material body and the physical sense organs

The second of the above might relate to sensation:


  "sensation" or "feeling" (Skt., Pāli वेदना vedanā; Tib. tshor-ba): sensing an object as either pleasant, unpleasant or neutral



Do the next three parts of the definition of dukkha relate to the next three skandhas? If so can you please explain how they're related (i.e. how each of the other three skandha are dukkha)? Are "association", "separation" and "not getting what is wanted" each associated with three different skandhas? Or is that all skandhas are equally able to be a type of "clinging" or attachment?
They are related to all aggregates.


Birth is the arising of aggregates. Death is the disappearing of that which arose. Ageing is the changing in between.
Sorrow, lamentation, pain, grief, &amp; despair are all Dukkhas caused by clinging to the five aggregates.
Association with unbeloved is the association with painful experiences(five aggregates). 
Separation from the loved is the separation from pleasurable/neutral experiences(five aggregates).
Not getting what is wanted means not being able to control the five aggregates at will: Not being able to retain pleasurable/neutral experiences. Not being able to keep away painful experiences.
