Once you are forced to think outside casually accepted, but conflicting, traditional frames of thinking, there's plenty of work to be done relating games to previously established sub-genres (across national borders, in some cases) or making new ones. There's a lot to discuss, which, for the most part, I'm less passionate about to declare things one way or another. The nature of sub-genres, mainly with highly related ones, is that they are less distinct from each other and as go deeper (e.g., sub-sub-genres) exceptions become the norm. This would actually be a nice change of pace compared to being so confused that you are denying Dark Souls is an action game and thus should be treated as one side by side with the other action games that arbitrarily don't appear in these "JRPG" threads. With that said, I'm going to provide some simple, inconclusive thoughts to your questions. This is partially because I haven't played most of those games. I'll still try to get by with what I know.
Isn't Grandia 3 like Valkyrie Profile 1? Correct me if I'm wrong. In that case, it is an interesting scenario where you tack-on action mechanics to what is otherwise a JRPG. Personally, I have no problem with JRPG being highly reflexive (FFXIII being a good example, with its rapid class switching), but it's certainly something to think about. I would call it a hybrid game at most, leaning towards of just JRPG.
3D Tales is definitely an interesting one. I've been trying to wrap my head around it since I played Tales of Grace F, the only one I've put much time in (the only one I've played besides a little of Vesperia). My mind immediately connected that game's movement system (within a confined area, no less) with Virtua Fighter 5, which I was also playing a lot of during that time. Skipping straight to the point, it really reminds me of a "squad-based" 3D Fighter (with the 2D ones not too far from 2D fighters in that same respect) and I only feel more comfortable with this line of thinking when you consider the fact that these games are usually multiplayer enabled (wouldn't be the first time a co-op fighting game has existed) and the AI/scripting taking over in the place of other players (poorly, if you ask me; I really disliked moving my characters games in that it's exactly what it sounds like: a 3D fighter where you control four characters in real time with one controller lol). I totally understand why someone many call me crazy at this point, but that's part of the fun (I also think this one is dipping into a rarely touched upon issue, what makes fighting games what they are, but one headache is enough for now). I'm not entirely confident in calling them fighters or anything, but in a process of elimination I've taken out the usual suspects. (Isn't Star Ocean highly derivative of Tales? The only one I played (2) was a lot like it, but pseudo-3D, like a belt-scroll game IIRC)
Resonance of Fate is a SRPG. IDK, seems open and shut to me.
Lightning Returns looks really weird to me. I have to play myself before I even try to categorize it. Unless movement has no real effect (as is the case of FFXII, IIRC), it's pretty safe to call something other than a JRPG. If it sounds really unintuitive given the game is carrying over a lot of tropes from the previous two games, imagine what would happen to House of the Dead if you suddenly gave the player full control of the camera/movement. Ah, yes, light gun/rail shooters are great analogue to the JRPG.
