All the statements about the Moon are correct. It revolves around the Earth from west to east, its day (the time it takes to rotate once on its axis) is equal to about 29.5 Earth days, which is also the length of its orbit around Earth, making a lunar day equal to a lunar month, and its orbit around Earth is elliptical, as are all orbits due to the laws of celestial mechanics.
