On the one hand you speak about attributes being the identity of a thing (implying a Kantian thing-in-itself), ... and in the very next paragraph you reject momentum, spin, mass, charge, coherence etc as being 'inherent' to things.
A thing is whatever it's attributes are. Do you think a thing's attributes are one thing and the thing, itself, something else?
I do not care if you want to attribute things to me that are not true but just to clarify what I mean, I have no use for Kant whose ideas I regard as the worst in philosophy after Hume. To say a thing is whatever its attributes are only means that any existent, to be an existent, must have some nature and whatever that nature is, that is what the thing is. The attributes only describe that nature.

I only mentioned position, momentum, energy, duration, and spin, but that's right, momentum, spin, and none of the others I mentioned are inherent in a thing. A thing's mass is inherent because it is one of a things attributes, but its momentum is a function of motion, normally written, p = mv, momentum equals the mass times velocity. A thing would be the same thing if it were not moving at all. Of course energy is also a function of motion, E = 1/2 m X V^2, kenetic energy equals one half he mass times the velocity squared. Again a thing would be the same thing no matter how little or much energy it had. It is also true of spin; whether spinning or not a thing is the same thing. An entity's mass, size, density, physical structure, state at a specific temperature and pressure (gas, liquid, solid), are inherent attributes.

According to you a thing's mass depends on its nature.
No. According to me a thing's mass is one of a thing's attributes.

You reject physics and speak about
noumena and knowing the nature of things, while you accusing me of metaphysical errors.
I have certainly never said anything that is a rejection of physics, or any science including chemistry and biology. I do reject a great deal of nonsense those claiming to be scientists say, but I do not reject science at all. Within the realm of the physical it is the only means to knowledge about existence.
I still think you confused the ontological nature of existents with epistemological knowledge of that nature. It's not an accusation, it's just an observation. I'm not judging you. If possible I would like you to understand why I hold the views I do. You don't have to agree, and where you don't, if you could provide specific criticisms of my reasoning, it could be helpful, but not generalities that label my views as derived from some crackpot philosopher.

Once I have identified what an apple is, it does not matter if it is still hanging on a tree, is half-eaten, is fresh, or rotting, it is still an apple.
You are confusing nature with essence.
I do not use the word essence only because it is philosophically loaded and smacks of Platonic realism. Nevertheless universal concepts do identify classes and categories of existents that have the same necessary attributes that make them the kind of things they are. In that sense, an apple is an apple, epistemologically, because it has the same necessary attributes as all apples identified by the universal concept, "apple;" but that is only true because apples, ontologically, have those attributes.
