Just want to point out that different characters refer to the beasts using different names. The king (AND the narrator) first referred to them as Guardian Spirit Beasts, while Kurapika was the first to call them Nen beasts. Biscuit and Bill first mentioned its sub category "parasitic Nen/parasites". It's clear everyone of these 4 had different experiences thus chose different names. The king is aware of the succession battles in his royal family and the beasts task, so he or some of his ancestors must came up with the name "Guardian Spirit Beast". Kurapika is not, he only sees them as regular nen beasts so he names them accordingly. And since he broadcasted that name in his emergency call (while using all channels) all Princes came to know them also by that name. Actually mentioning the word "Nen" in Nen beasts is the reason Theta is in her current peril with the 4th prince. Which in fact was Kurapika's intentions since he wanted to reach a stalemate by teaching everyone about this power. Ironically Luzurus was the only prince to call them "Guardian Spirits". This could simply be a coincidence, since the name is pretty self-describing anyway "an invisible spirit that guards you"

In short I believe GSB is undeniably the correct name since it was chosen by the king/narrator themselves who best know about the nature of the beasts' abilities. I also just checked the raws of chapter 162 and it's indeed the same 念獣/Nenjuu as the recent chapters so it can't be something different.

I think it's a matter of prespective here. Kurapika doesn't know about GSB or Parasites/parasite-type Nen. So he saw them as something he's familiar with i.e. Nen beasts. Not to mention he had underlying intentions of reaching a stalemate. I'm not sure if this assumption is entirely wrong or partially right. The latter is true if the Nen beasts happened to be a bigger category that includes GSB.

Biscuit and Bill are more knowledgeble and are aware of the parisitic-type Nen, so they referred to them as such. This is pretty much a confirmed larger category that GSB lie into.

The other princes received the words "Nen beasts" from the clueless/scheming Kurapika, and "parisitic" from Biscuit. The guards combined the two pieces information and referred to them as "parasitic Nen beasts"

There's 2 possible ways to view the subcategories:

1. Nen Beasts>Parasitic Nen Beasts>Guardian Spirit Beasts

2. Nen Beasts (something different)

 Parasitic Nen>Guardian Spirit Beasts

The only thing I'm certain of is GSB is its own subcategory of parasitic nen since they are more related to Kakin royal family and have the properties of draining the host's aura. The fact whether the parasitic Nen is also another subcategory to nen beasts is unclear to me... Only real evidence is Kurapika naming them by that, but this is was only an assumption and/or a ploy.

For whether it's conjured or emitted. Bill claimed that "many of the Parasites are conjuration based". The perspective here is important as you see Bill never talked about the GSB that the wiki page is all about. He also said many, not all. Perhaps GSB is the exception subcategory of that "many" seeing their properties, as you said, leans more to emission than conjuration.

1. Nen Beasts>Parasitic Nen Beasts>Guardian Spirit Beasts

''2. Nen Beasts(emission, most of what we've seen)''

 Parasitic Nen("many are conjuration based")>Guardian Spirit Beasts(emission) 

 Option 2 makes more sense to me now... since it would be weird to see a mostly emission category having a mostly conjuration category that has an emission subcategory. right?

This 3rd option simply cannot be true..

<p style="font-weight:normal;">3. Nen beasts(emission)>GSB(emission)

<p style="font-weight:normal;">Parasites(conjuration)(separate category)

<p style="font-weight:normal;">Two reasons: GSB share many similar properties to parasitic Nen. 2. Biscuit confirmed the GSB to be parasitic XD. We can't question her!
