Lots of good questions here, firstly, creating a Phoenix would require an enormous amount of skill with the chosen spell. It would also require a complete mastery of the fundamentals of Kido, including knowing all 198 numbered spells. That's the sort of skill neccessary to create a Phoenix, as what you're essentially doing is binding the spell into a semi-corporeal form and imbuing it with magical life. That sort of thing is beyond even most members of the Kido Corps, as the spell itself would be highly complex and disasterous if performed incorrectly, to be capable of creating a Phoenix would be sign of great skill and would lead to good status and prestige within the corps. For such an ingenius act of spellmanship.

Hiroya would know how to create a Phoenix, but Kazuya would not. It's simply put not his field of expertise, it's essentially a form of Sozodo (Way of Creation), talents of that nature are outside the scope of the simple magics practised within the Gotei 13 altogether, and are unusual even within the Corps, where only a handful of specialists exist.

A sentient Phoenix would be an impossibility, it literally could not happen. It would be an existence marked by an almost slavish dedication to the nature of the spell that gave it birth, any Phoenix created by a fire spell would be unruly, untamed and wild - it could be directed, not really controled per se, although it would be inclined more so than forced to follow it's creators commands. A Phoenix created by a wind spell would be quiet, yet freespirited and particularly agile in flight.

No, they likewise cannot reproduce, even if they had the means they would not have the instincts to actually do anything. Hybrid Phoenixes would likewise not be a thing, they're not a race, they're a form of magical construct, more similar to a Shikigami than anything else really.

As for the box animals, that's a possibility, although it would be a very dangerous subject, perhaps something currently studied by the Kido Corps as an addition to the Gotei 13? It would be nothing alike the Hitman Reborn concept however. You could definitely mass produce smaller ones, although their lifespan would be dramatically reduced, and they would have a limited number of "rebirths" to compensate, and much less actual power than a proper Phoenix.

As for the scale of their powers and whether they can learn new spells, the answer to the second question is simply "No". A Phoenix doesn't have the mind neccessary to learn spells, neither does it have the means to cast them, see, when a Phoenix attacks it does not so much cast the spell it was born from as it wields it's own magical essence as a form of attack. The reason for that is simple, they don't possess any spiritual energy of their own whatsoever, they're limited by a set capacity, once that capacity is used up, they'd dissipate for a while until they'd be reborn with full power. Their maximum capacity is dictated by the full power of the spell that gave them life. The more powerful the spell was, the more powerful the resulting Phoenix would be.

Now finally, for the Shunkou question, the answer would be a resounding YES!
