Some viruses have a capsid with proteins that act as "docking stations" so that they can attach to host cells. Others without capsids also have a different type of protein that does the same thing.
Yes, during the viral life cycle, RNA is synthesized from viral DNA by a process called transcription. This RNA serves as the template for protein synthesis, which is carried out by the host cell's machinery. This process allows the virus to replicate and produce more viral particles.
Messenger RNA
Hepatitis B virus is made up of only one protein called the core protein, which forms the viral capsid.
Interferon is the substance that causes noninfected cells to form an antiviral protein. It is produced by the immune system in response to viral infections and helps neighboring cells defend against viral invaders.
The HA protein of influenza virus mediates viral attachment and entry into host cells by binding to sialic acid receptors on the surface of the host cell. It is a key protein for viral infectivity and is also the primary target for neutralizing antibodies generated by the host immune system.
Interleukin
Protein of course :P
To carry out their Viral processes they 'utilize' the resources of The Host Cell.

Viruses are composed of protein and DNA. The DNA encodes the protein as well as the DNA for the virus. Viruses depend on host cells because they are incapable of reproducing themselves. They enter the host cell and the viral DNA is inserted into the host DNA. The virus then "hijacks" the host cells replication machinery to make more viral protein and viral DNA.

Interferon
It is shed like any overcoat and recycled.
