Plasma is highly ionized atoms. This results in extremely energetic ions, and these ions carry an electrostatic charge. The tokamak is a container with magnetic fields for boundaries. The plasma is a moving group of electrostatic charges, and moving charges create magnetic fields. The magnetic field thus created interacts with the magnetic field set up in the tokamak to deflect and thus confine the charged plasma.

Who invented the Tokamak?
Do people know what TOKAMAK is? I mean how it translates. тороидальная камера с магнитными катушками A Russian acronym. Quote from wiki: "In 1968, at the third IAEA International Conference on Plasma Physics and Controlled Nuclear Fusion Research at Novosibirsk, Soviet scientists announced that they had achieved electron temperatures of over 1000 eV in a tokamak device. This stunned British and American scientists, who were far away from reaching that benchmark. They remained suspicious until tests were done with laser scattering a few years later, confirming the original temperature measurements." Nothing else to add actually. Russians invented it, way before western scientists by the way.
Why is it difficult to get fusion reactions to work?
The best apparatus yet devised is the tokamak where a plasma, that is a stream of ionised gas, is heated in a toroidal evacuated chamber, whilst the stream of gas circulating around the toroidal chamber is heated to several hundred million degrees C. The stream of ionised gas is kept stable by magnetic fields. The difficulty is just getting the plasma hot enough and stable enough, and a lot of power is required to get a short burst of fusion to start. A much larger tokamak is to be built caled ITER and this will probably be a big advance, but it is going to be a long project and won't have much to show for probably another ten years.You can look up ITER in Wikipedia.
What temperature is required for fusion to happen?
In tokamak reactors, approx 300 million degC

What is the toroidal chamber used to produce fusion reactions in heated plasma?
tokamak
Where is the 4th state of matter found?
Plasma is confined in a magnetic field. If it touches anything it will not be plasma anymore.

What tool can be used to push or hold plasma?
If you are talking about high temperature plasma (with the plasma being a mass of ionized atoms), then a magnetic field would the thing that can effectively push or hold plasma, presuming that you want the plasma to remain a plasma. This means that you would need electromagnets to generate and manipulate magnetic fields. In nature, these fields can be generated by the Earth, Sun, Jupiter, etc. In technology, a tokamak is used to hold high temperature plasma as efforts are made to induce fusion.
What is a toroidal chamber?
Tokamak
Which one of the following countries has currently largest tokamak type reactor and created first plasma?
You don't give the list of 'following countries' ! However I believe the largest or most powerful tokamak so far is the JET at Culham in England. See link below. The new one in S Korea looks perhaps to surpass that but it has not yet been fully operated. The tokamak originated in Russia, it was a brilliant development which took western science by surprise, but is now pretty universal in fusion research. The other possible lead is by laser ignition which is being promoted in a few places, but is very difficult to set up accurately. There is a Wikipedia article on 'tokamak' which gives a long list of facilities in many countries.

How is electromagnetism used in containing nuclear fusion reactions?
The earliest attempts at fusion reactor design used magnetic confinement to compress the fuel plasma as well as keep it away from the reaction vessel walls. The best such designs were derived from the Russian tokamak toroidal reactors. Newer attempts use inertial confinement (like H-bomb secondaries) and have come much closer to break-even than tokamak types have. No magnetic fields are used here.
Stars are made up in the the what state?
The material of stars exists in the plasma state, where the electrons have essentially been stripped from their regularly confined orbital "areas of probability."
How hot must the core of a protostar be to begin nuclear fusion?
When the core of a protostar has reached about 10 million K, pressure within is so great that nuclear fusion of hydrogen begins, and a star is born.
