Yes. In as much as the field lines are IMAGINARY lines in the first place - like the isostatic lines you see on a weather map - or the lines of longitude and latitude on the Earth's surface. Each line forms an unbroken circular interval - a loop - a closed circle, ellipse or a more complexly bent shape.
In fact, they actually form SHEETS in 3D space, in the forms of spheres - or distortions of spheres. They are defined from the 2nd of Maxwell's Equations - which reads, in english: " the surface integral of the magnetic field is zero," meaning, again, that it is a closed loop (or spheroid.)

False.
No. Magnetic lines curve out from one pole and end up at the opposite pole. Please see the related links for illustrations.
False.
If you think of the planet Earth as a very large round magnet, you can imagine the magnetic lines of force that come vertically out of the magnetic poles, then curve around to reach the opposite pole where they vertically return to the planet from the opposite direction. While the lines of force are parallel to the surface of the Earth, they are horizontal.
no they are not

It has No magnetic interaction
Magnetic field lines spread out from one pole, curve around the magnet, and return to the other pole.. . ah, they don't actually spread out from the poles, inside the magnet they are bunched together but they still form closed loops with the lines outside.
They are called the magnetic field lines.
Magnetic field lines don't cross.
False.
Among the field lines generated by a circle current, the one which passes the center is not closed. --JF Hu
