If by 'replaced' you mean, can the body grow new ones like with blood and tissue cells, then no, not at present. There is some promising research being done with stem-cell therapies, but they're a long way from being able to effectively regrow nerve tissue.
Nerve cells typically do not continue to divide once they are fully formed. Unlike skin cells and epithelial cells that undergo continuous division for repair and maintenance, nerve cells have limited regenerative capacity. Once nerve cells are damaged or lost, they are not easily replaced, which contributes to the challenges of nerve regeneration in the body.
well rods and cones aren't cells, they are nerve ending. so I'm assuming if the nerve does die, the rod or cone will die along with it.
Cells
Because those cells lack the ability to divide. Once nerve cells specialize from stem cells, they lose the ability to go through mitosis

a nerve tends to refer to a group of nerve cells.
Yes, modern neuroscience research has confirmed the existence of neurogenesis, even in the adult brain.
Connector nerve cells connect the sensory nerve cells with motor nerve cells and allow for decision making.
Nerve cells, also known as neurons, generally do not reproduce or regenerate in the human body. Once they are damaged or lost, they are not easily replaced. This is why injuries to the nervous system can have long-lasting effects.
ganglion cells
Yes, dogs do have nerve cells.
A nerve cell is the structural and functional unit of a nerve
