A double-displacement reaction is characterized by the fact that bonds of the reactants are changed.
When many were taught chemistry in the 1970s this was called a double decomposition reaction. It is now called a salt metathesis reaction and also double displacement reaction. There are examples and more information at the related link.

Yes, a double displacement reaction can also be a redox reaction if there is a transfer of electrons between the reactants. This transfer of electrons leads to changes in the oxidation states of the elements involved, which is a characteristic feature of redox reactions.
You can find online calculators for single displacement reactions on various chemistry websites or through chemistry apps available for download on your smartphone or tablet. These calculators can help you predict the products of the reaction based on the metals involved.
The reaction between BaCl2 and Na2SO4 is a double displacement reaction, also known as a precipitation reaction. In this reaction, BaSO4 and 2NaCl are formed as products when BaCl2 and Na2SO4 react. This reaction involves the exchange of ions between the reactants to form new compounds.

Also other elements can be involved.
They aren't. Double displacement (metathesis) sometimes forms a precipitate, but not always, and it would be silly to call it a "precipitation reaction" if no precipitate was formed. Formation of a precipitate is, however, one way to tell that a reaction has occurred. If everything just stays in solution, then it's meaningless to call it a "reaction" since there has been no change. The evolution of a gas is another method for determining that a reaction has occurred, as is a change in color (this often indicates a change in oxidation state as well, though not always).
Zn(s) + 2AgNO3(aq) --> Zn(NO3)2(aq) + 2Ag(s) is a single displacement reaction. It is also called a single replacement reaction. As you can see, the zinc displaced, or replaced, the silver in the silver nitrate solution.
1) Formation of a precipitate 2) Usually there is a colour change. 3)Neutralization reactions (also a double displ. reaction) involving an acid and a base form water which is a clue.

Double displacement means that two elements are displaced. This can be simple, as in WX + YZ -> WY + XZ, but it could also be much more difficult, depending on the complexity of the reaction. The only guaranteed way to discover the products is to allow the reaction to take place, then look at the results.

yes
They are established studying the reaction of metals with water and acids and also single displacement reactions.
