No, it would be 2 animal companions, one as if you were 9th level and the other as if you were 5th level, the levels do not stack on themselves IIRC, and Boon Companion only applies to one animal companion per use of the feat.
Benefit: The abilities of your animal companion or familiar are calculated as though your class were four levels higher, to a maximum bonus equal to your character level*. If you have more than one animal companion or familiar, choose one to receive this benefit. If you lose or dismiss an animal companion or familiar, you may apply this feat to the replacement creature.
Special: You may select this feat more than once. The effects do not stack. Each time you take the feat, it applies to a different animal companion or familiar.

Hm, I just found
If a character receives an animal companion from more than one source, her effective druid levels stack for the purposes of determining the statistics and abilities of the companion.
So it would seem, you would get one AC and the levels would indead stack and your AC/your effective druid level is bolstered by Boon Companion.

thanks again so my time and concept wasn't a complete waste of time .
Keep in mind that if this is for PFS, you can only have one combat animal active per scenario.
