Nitrogen does not bind to hemoglobin in the way that oxygen does. Hemoglobin specifically binds to oxygen molecules for transport in the bloodstream. While nitrogen is present in the air we breathe, it is mostly inert and does not participate in the same biochemical interactions as oxygen with hemoglobin. Instead, nitrogen is dissolved in the blood but does not play a role in oxygen transport or exchange.
The oxidation state of iron in hemoglobin is +2, known as ferrous iron. This form of iron allows hemoglobin to bind and transport oxygen in the blood.
A hemoglobin molecule can bind up to four oxygen molecules, one at each of its four heme iron sites.
Each hemoglobin molecule can bind up to four oxygen molecules.
It is not the fourth one specifically that binds easier, O2 is a positive allosteric effector (activator) of Haemoglobin and the binding of O2 facilitates further binding of O2. I'm not sure why this is though.
The structure of hemoglobin, with four protein subunits and heme groups, allows it to bind to and transport oxygen efficiently. The heme groups in each subunit bind to oxygen molecules, enabling hemoglobin to carry oxygen through the bloodstream to tissues and organs. Additionally, the quaternary structure of hemoglobin facilitates cooperative binding of oxygen, meaning that as one oxygen molecule is bound, it increases the affinity of the other subunits for oxygen.
A gaseous hormone that can bind to hemoglobin and be released to cause local vasodilation is nitric oxide. Nitric oxide is also known as nitrogen oxide.

Mostly oxygen.
Carbon dioxide and BPG bind to amino acids located on hemoglobin. Oxygen molecules bind to the iron molecules located in the heme. Each hemoglobin molecule can carry up to four oxygen molecules, one on each of the four iron molecules. Nitric oxide can also bind to hemoglobin when either oxygen or carbon dioxide are bound to the hemoglobin.
Up to 4.
Oxygen and carbon dioxide are the two chemicals that bind with hemoglobin in the blood. Oxygen binds to hemoglobin in the lungs for transport around the body, while carbon dioxide binds to hemoglobin in the tissues for removal from the body.
Hemoglobin is a complex protein with iron groups inside it that bind to oxygen.

Oxygen and carbon monoxide
Haemoglobin combines with four molecules of oxygen.
Hemoglobin cooperativity is a process where the binding of one oxygen molecule to a hemoglobin molecule makes it easier for other oxygen molecules to bind. This means that as more oxygen molecules bind to hemoglobin, the affinity for oxygen increases, allowing hemoglobin to efficiently transport oxygen in the bloodstream.
Carbon monoxide binds to hemoglobin with a higher affinity than oxygen, forming carboxyhemoglobin. This can displace oxygen from hemoglobin, reducing the blood's ability to transport oxygen to tissues, which can lead to serious health consequences.
