Curves yes, straight lines no
Two curves which intersect at right angles, ( the angle between the two tangents to the curve) curves at the point of intersection are called orthogonal trajectories. The product of the slopes of the two tangents is -1.
There are none. Those two curves do not intersect.
The answer could be "intersect". If not, please edit the question to include more context or relevant information, and then resubmit.
Every polygon has two of its sides intersect.
Curves yes, straight lines no
This is because the intersection would be impossible. If they crossed then they would have the same utility rather than being two different curves.

I assume you mean curve touching? It means that two or more curves intersect at a single point (tangent point).

Lines, curves, planes, solid shapes are some.
no
indifferent curves are convex to their origin, they do not intersect, and have a negative slope
