Yes. A 747 has a glide ratio of approximately 15:1. It can glide about 15 miles for every 1 mile it decends. British Airways found this out when their flight 9 lost all 4 engines due to volcanic ash near Jakarta, Indonesia 24 June, 1982.

Why does other air crafts uses 4 engines to fly while others use 2 engines?

It's a question of trade offs and compromises. Two engines are easier to deal with than four engines, you'll only have two throttles, two fuel systems, two oil pressure gauges etc etc. OTOH, to get the same power out of two engines as you would have out of four, each engine has to be doubly powerful, and that's a problem too. It'll be bigger, heavier, might run warmer etc. And if you lose one out of two engines during flight, that's a much bigger problem than losing one engine out of four.

Is a reflection and glide the same thing?

No, a reflection and a glide are not the same thing. A reflection is a transformation that flips a shape over a line, creating a mirror image. In contrast, a glide involves two transformations: a reflection over a line and a translation along that line. Thus, while both involve flipping, a glide also includes a movement, making them distinct concepts in geometry.
