High Temp and high pressure
Yes, high pressure is required for a fusion reaction to occur because it helps bring the nuclei close enough together for the strong nuclear force to overcome the electrostatic repulsion between positively charged nuclei. The high pressure creates conditions similar to those found in the core of stars where fusion naturally occurs.
It isn't, in general. Thermonuclear bombs use a fission bomb to generate the heat and pressure required to start the fusion process, but there are other ways of doing it (stars do so by gravity, for instance).
A helium nucleus, also known as an alpha particle, is formed during a solar nuclear reaction by the fusion of four hydrogen nuclei.
One significant difficulty in using fusion as an energy source is the challenge of containing and controlling the extremely high temperatures and pressures required for the fusion reaction to occur.
A fusion reaction generates helium as a waste product.

The helium nucleus is formed during the proton-proton reaction by the fusion of four protons. Two of the protons are converted to neutrons by the weak interaction.

Problem on nuclear fusion is upon confinement of reaction in earth atmosphere. Nuclear fusion required very high temperature to initiate the reaction. Sustaining reaction is not easy. It is likely the earliest nuclear fusion will be available commercially by 2050. It is a little far future for the current energy crisis would reach it peak around 2040.
One significant difficulty in using fusion as an energy source is the challenge of containing and controlling the extremely high temperatures and pressures required for the fusion reaction to occur.
In a fusion reaction, the total mass of the reaction products is less than the total mass of the initial reactants due to the conversion of mass into energy according to Einstein's famous equation E=mc^2. This difference in mass is known as the mass defect, and the lost mass is converted into energy during the fusion reaction.
No, fusion is a type of nuclear reaction.
A fusion reaction generates helium as a waste product.
Change of H of fusion (∆Hfusion) is the enthalpy change going from solid to liquid or liquid to solid. That is, it is only for the phase change, and it is not accompanied by a change in temperature. It can be related to the ∆H of reaction but one would have to know the reaction to be more specific.
During a solar nuclear reaction, the type of nucleus formed by the fusion of four nuclei is a helium nucleus, also known as an alpha particle. This process is known as nuclear fusion and is responsible for the energy production in the core of the Sun.
