Light travels in straight lines. The only way to curve light is to obtain inside something that holds in the the light. For example, a plastic curved tube will carry light.
Light travels in straight lines. However, 'straight' ain't what it used to be. Our current understanding of the universe suggests that mass causes a localized distortion in space time, effectively curving space around itself. As a beam of light approaches a massive object, it can be affected in this way as it passes through the curved space. From outsie, it appears to travel in a curved path, but as far as the light is concerned, it's moving in a straight line -- it's just that the straight line exists in a curved reality, if you follow me.
It's always straight - as far as the light is concerned. If space is curved then the light follows the curve.
yes
Very often tornadoes, will travel in a straight line, but many do not, following meandering or curved paths instead.
Line travels in straight lines, under the principle of least time, aka Fermat's Principle. Light can be refracted at the boundary between two media meaning the path is bend but both parts of the path remain straight lines. Technically, light follows a space-time geodesic which might be curved, but locally this is too small to detect.

As particles photons travel in a straight line unless they are diverted by reflection, refraction, or a magnetic or gravitational field. Note that when it comes to gravity it can also be represented that the light continues in a straight line - but the space it travels through is curved so its path appears curved to the outside observer.
A curved line is a line that is curved.

yes
Kepler's Law: "The orbits of the planets are ellipses with the Sun at one of the foci."

Yes, technically a curved line can be a line segment, a line in general is something that can be curved or straight

Yes true
Straight line.
a curved line is a line that is bent without angels
