No we can't because when your Pokemon faints, you can revive them. Though I assume that when left in a bad condition it could die. However when Ash let a Pidove faint, it revived nlt so long ago
However 2 Pokemon are known to have deceased in the anime
Latios and Lucario
Both died sacrificing their lives to save a multitude of people
Not to forget that Arceus almost died after it had been hit by the devastating comet. Again this was done as a sacrifice
Pokemon have souls just like the soul dew is actually the soul of Latios, meaning Pokemon don't turn into ghastly when they die
Ghost type Pokemon are usually peoples souls that have possessed objects, just like Yamask being a human soul that possessed a mask. The faces of Yamask are the faces they used to have in their previous life
Also, Honehedge is a human's soul that has possessed a sword
This can also be assumed for Chandelure since it is basically a living Chandelier. It's ability to scorch peoples soul would make me state that it is a human that died whiles baring a grudge
As ghost type Pokemon are usually associated with sinister taughts
