- UPDATE -
However there are Orthodox Churches and Orthodox followers in almost every country around the world.
Russia and Greece
There are two Orthodox churches.
The Eastern Orthodox (Greek) and Eastern "Oriental" Orthodox (Coptic which is Egyptian but the Arabs took over so they had to speak Arabic instead of Coptic).
They are the same but differ in the view of the divinity of Christ the Eastern Orthodox believe that Christ has two natures but are separate while the Eastern "Oriental" Orthodox believe Christ had two natures but united.
They both have apostolic succession the Greek church founded by St.Andrew and the Coptic church founded by St.Mark.
Over time the Greek Orthodox church spread to Serbia,Russia,Bulgaria and most of eastern Europe and granted them their own Patriaches.
The Coptic Orthodox church gave Syria, Ethiopia,Eritrea,India and Armenia their own Patriaches.
some of the countries that have a decent amount of orthodox christians are Russia, Greece,Egypt, Armenia, Eretria, Ethopia, Syria, Serbia, and Bulgaria

80 %
Eastern Orthodox religion is strongest in countries such as Russia, Greece, Romania, Ukraine, Bulgaria, and Serbia. These countries have a significant proportion of their population following the Eastern Orthodox faith.
The majority of Serbs follow Serbian Orthodox Christianity. It is a major religion in Serbia and holds significant cultural and historical importance for the Serbian people.
In modern Greece, most follow the orthodox religion which practices baptism.
Mostly Greek Orthodox which is christian.
What do you mean by this questions? If you refer to religion, Romanians are Eastern Orthodox. I was born in Romania, but I do not understand what you mean by "What do Romanias follow?"
Mostly Oriental Orthodox branch of Christianity. But also Catholics, Protestants etc.
Orthodox Jews generally follow a custom of never setting foot in a house of worship for another religion, though there are a few Orthodox Jews that will.
That depends on the countries and on whether the Jews were orthodox or Reform. In Germany, for example, the majority of Jews were NOT orthodox and dressed very inconspicuously - as in many other countries.
