We have created 20 nanograms of antimatter. To get you on track, one nanogram is a billionth of a gram.
Antimatter is very hard to make, so far only a very small quantity has ever been produced;
much less than a milligram has ever been produced and yes there is a way to store it. It's called the penning trap.
The penning trap is a container in extreme vacuum and magnetic fields. This is to prevent the antimatter from touching air, since air is made of matter.

Antimatter is a concept. It is also particles composed negatively.
They annihilate each other, releasing a relatively large quantity of energy, which can be calculated using the formula e=mc2, where e is the released energy in joules, m is the mass of the particles in kilograms, and c is the speed of light in metres per second
Anti matter does NOT exist. As soon as it is in contact with matter which is anything ; solid , liquid , gas, they are both annihilated. You can think of antimatter as protons with a negative charge and electrons with as positive charge. So Proton^+ Proton^- = Annihilation (??? Energy) Electron ^- + electron^+(positron) = Annihilation (???? Energy).

As much as 50% of energy produced in reactions between nucleons and antinucleons is carried away by neutrinos in these applications. It is theoretically possible to retain as much as 100% of the energy in an Antimatter reaction.
Not much; as soon as the antimatter meets with normal matter, they annihilate (destroy) each other. That doesn't leave you much time to build anything; a few small atoms have been built, though.
There are no definite answers with our current level of understanding of antimatter at this point but scientists believe that this is the result of an imbalance in the production of matter and antimatter particles in the early universe. Another explanation for this phenomenon is that Antimatter may exist in relatively large amounts in far away galaxies due to inflation in the primordial time of the universe
It may have to do with the way the universe was created. Certainly if there was a lot of antimatter created, much of it may well have come in contact with matter through the billions of years the universe has existed. That would have resulted in the conversion of that antimatter (along with a like amount of matter) into energy. There may not have been much antimatter around to begin with, too. But, since the amount of visible matter represents less matter than has been calculated to exist in the uinverse, it may be that there is a good bit of antimatter out there somewhere. Not likely, but possible.

Pretty much only humans go by names
In theory, antimatter could be used as an extremely concentrated form of fuel, to run power plants, to propel rockets, or anything else that requires fuel. However, it is extremely difficult to store, requiring special magnetic containment since any contact with matter causes a big explosion. Unless some efficient solution is found for the storage problem, I doubt that antimatter will ever be used for much other than research into subatomic physics.
i think 60%
$25 billion for a gram of positrons. $67.5 trillion for anti-hydrogen
Yes, the universe does contain antimatter, which does naturally occur, although in quantities much smaller than matter. The very slight bias of physical law in our universe towards towards matter instead of antimatter is a subject of ongoing research; some calculations indicate that for every hundred billion particles of antimatter created from the energy of the Big Bang there were roughly a hundred billion "plus one" particles of matter - the balance eventually annihilating each other during collisions, resulting in a universe almost entirely of normal matter. Regions of space currently rich in antimatter have been searched for without success to date. Very tiny amounts of light antimatter particles do exist in cosmic rays; radioactive materials can spontaneously produce antimatter particles when they decay; and it can be produced in particle accelerators.
