Yes.
A rebar, or reinforcing bar, is a common steel bar, and is commonly used in reinforced concrete and reinforced masonry structures. It is usually formed from carbon steel, and is given ridges for better mechanical anchoring into the concrete. It can also be described as reinforcement or reinforcing steel. In Australia, it is colloquially known as reo.

I assume they would be tied using tie-wire to the rest of the rebar cage.
I think the bar along the span is main bar
The numbers refer to the different diameters of the rebar used to reinforce the concrete. R specifies round bar. Y or N specify deformed bar. See below. == * Round mild steelreinforcement bar - R6 R10 R12 R16 R20 R24 R28 R33 * Deformed reinforcement bar - N12 N16 N20 N24 N28 N32 N36 * Stock lengths of reinforcement bar - up to 12 metres * S12 Pool Steel - Mild steel bars (not tempcore) that is very easy to bend by hand * Processed reinforcement bars - custom cut and bent to required needs * Dowel Bars - precut, often galvanised round bars used when one slab joins another * Galvanising - Plain Reinforcement Steel bars can also be supplied galvanised *Deformed Bar was previously called Y-Bar eg: Y12, Y16 but through product improvements the tempcore strength was increased (now 500Mpa) and is now denoted as N-Bar as listed above
A cover meter determines the distance from the outside face of the concrete to the depth of the reinforcement bar.
shear reinforcement
The reinforcement may be in the form of "mesh" or rods. The steel reinforcing rods are colloquially called rebar(reinforcement bars).
The weight per meter of a 20mm diameter rebar is approximately 2.47 kilograms.
Rebar is an informal term for steel "reinforcing bar". These are steel bars that are placed within the structure before the wet concrete is placed. Steel reinforcement is necessary for almost all structural concrete because concrete has virtually no tensile or shear strength. The rebar provides almost all of the resistance to tension and shear within the structure.
Deformed rebar has either indentations or ridges in a regular pattern on the bar surfae.
Black steel rebar is a type of reinforcement bar used in construction. It is made from carbon steel and has a plain surface finish, giving it a dark appearance. Black steel rebar is typically used in structural concrete applications to provide strength and durability.
Items used to reinforce concrete are wire mesh, rebar, and steel cables.
Rebar Detailing is a procedure of making shop drawings for the steel reinforcement for the development procedure. The Rebar Detailing procedure incorporates the position, bending shapes, amount, description, laps of the reinforcing steel and measurements. The Rebar Detailing Drawings are made to incorporate the separating, area, rebar size and lap of steel. The Rebar Detailing Services includes: Rebar Detailing Services, Rebar Shop Drawings Services, Rebar fabrication Services, Rebar Framing Plan Design, Rebar Structure Foundation, Rebar Pit Design, Rebar Framing Plan, Rebar Beam Design, Rebar Structure Steel Detailing, Structure Foundation Rebar Detailing.

Some like to refer to the finished product as a woven basket of rebar, but it is not truly an over/under installation as the name suggests. An industry standard, # 3 rebar (# 3 referring to the diameter of the bar) is placed on 12" centers to create a mat of steel reinforcement. This is common practice for pool shells placed in stable soil without additional vectors of stress/weight. When non-typical vectors are present to act on the strucutral integrity of the pool shell, the reinforcement sizes and the spacing can be change to provide additional strength to the concrete structure.
it would depend entirely on the rebar design.....
No, epoxy is not required in rebar connections. However, epoxy can be used to enhance the bond between the rebar and concrete in critical applications where higher strength and durability are needed.
I assume they would be tied using tie-wire to the rest of the rebar cage.
