I have my doubts with the Absolute Zero resistance, like, if they are immune to it (not just are unable to die due AZ, but also do not suffer damage) then they logically shouldn't be affected by other ice type attacks (unless you argue those are supernatural based or such). Are we sure that move is AZ, or that being unable to affect other ice type pkm is not due the move's own weakness?
That could be the case. In the anime, even Normal-type moves or basic things like Peck can have natural augmentation that do things like making glowing energy beaks or such to augment the part being used to attack.
& in the case of an Ice-type move, Ice Beam's most recent description says:
"The target is struck with an icy-cold beam of energy. This may also leave the target frozen."
So they may indeed be supernatural.
Of course, it could be that they're not all as cold as Sheer Cold, which is the basis of the Absolute Zero Resistance; Sheer Cold is a OHKO otherwise. (Curiously, like with Toxic for Poison-types, Sheer Cold is more accurate when used by an Ice-type Pokemon.)
It might also be that some use different levels of energy (more or less) than Sheer Cold or Ice Beam. We know Sheer Cold is Absolute Zero because that's it's Japanese name AND it's stated as such in its descriptions.
As for the bone attacks, no, just cuz one attack is made using a bone does not means its bone manip (you do not gave bone manip to people that wields bone made weapons). As I stated previously, the typing most likely works more due attacks being infused by elemental energy.
Didn't we have a Weapon Control revision about making controlling weapons not being Limited Telekinesis?
If things like Cubone controlling 1 or more bones for things like Bonemerang isn't Bone Manipulation nor Telekinesis, then what is it?
As far as I know, femur bones don't travel in boomerang trajectories when thrown.
(Though it may be notable that besides Cubone & Marowak, Lucario & Mandibuzz (But not their pre-evolutions.), can also learn Bone Rush, but not other Bone moves, similar to Lunala learning Zorua & Zoroark's signature move Night Daze.)
