Yes modifying a car is legal. You can do almost anything to a cars engine, the only restriction is making sure its falls within regulation of the state/country's law on it. Answer to the question is yes, it is legal
No, they have very strict laws regarding modifying vehicles. They must be almost completely stock for legal use on the roadways. Many there have Mad Max replica cars and can't drive them.
They are either built by highly modifying a regular car (these are called "GT" class cars or "Grand Touring"), building them from scratch from a pre-built chassis or also highly modifying a street legal car (these kinds of race cars are usually owned by people who build them in their own shop to either drag race or take them to track day events), or like how Funny Cars or NASCARS (these are called "Stock Cars") are built where almost all of them look the same on the outside but underneath are parts that the company decides to put in (Chassis, engine, transmission, steering, suspension, brakes, etc.) as long as its within regulations.
yes, it is.
The word "legal" is an adjective. It stays the same whether it is modifying a singular or a plural noun.
