Yes, mature erythrocytes are still cells and are still living. In most mammals the circulating red blood cells do not have nuclei, so they are unable to repair themselves when damaged and eventually die due to the accumulated damage.
No, mature human erythrocytes have no nucleus.
I found that erythrocytes mature in the bone marrow closely attached to a macrophage.
No. Erythrocytes are produced by bone marrow.
A red blood cell that (in humans) is typically a biconcave disc without a nucleus. Erythrocytes contain the pigment hemoglobin, which imparts the red color to blood, and transport oxygen and carbon dioxide to and from the tissues.
There is no nucleus or chromosomes in a mature erythrocytes .
Erythrocytes (Red Blood Cells) - specialized for oxygen transport - mature erythrocytes have no nucleus instead these disk - shaped cells are packed with the respiratory pigment Hemoglobin *Hemoglobin is an iron containing molecule that binds with oxygen

If stem cells mature into erythrocytes (red blood cells), they will become specialized for oxygen transport in the body. Erythrocytes are responsible for carrying oxygen from the lungs to the rest of the tissues and organs, as well as removing carbon dioxide waste. They have a unique biconcave shape and lack a nucleus to maximize their capacity for oxygen-carrying.

No. Some cells do not in fact have DNA, probably because of the lack of a nucleus. For example, mature red blood cells (erythrocytes) do not contain a nucleus or DNA.
Cells that do not contain a "true" nucleus are called prokaryotes. Sometimes eukaryotic cells are anucleate(no nucleus) when mature. Erythrocytes (red blood cells) in mammals are an example of eukaryotic cells that do not contain a nucleus when mature.
