How many rays can be drawn through one point?
Infinitely many.
What is the minimum number of rays that can be drawn to locate an image?
To locate an image, only two non-parallel rays are needed. These rays intersect at the image point, which is the point where the image is formed.
How do to find the angle if two rays are given?
It depends on what information about the rays is given. If all you have is two rays drawn on a sheet of paper then you need to measure the angle using a protractor. If their equations are given - in standard or vector form, then there are formulae that will enable you to work out the angle between them.
How many light rays are required to locate the image formed by a lens?
Two light rays are generally required to locate the image formed by a lens. One ray is drawn parallel to the lens axis and then refracted through the focal point, while the other is drawn through the optical center of the lens without changing direction. The point where these two rays intersect is where the image is formed.
What is the formula for finding numbers of segment and rays given numbers of point?

How do you draw two rays that are not parallel to each other and never intersects?
that is impossible. if they aren't parrallel, and they're rays they have to intersect at some point. This is because rays spread at both ends. The above answer is only correct if the rays on drawn on the same plane or if they are drawn on convergent (intersecting) planes, so the correct answer is the two rays must be drawn on separate planes that are not convergent, since all non-parallel lines on the same plane, or on convergent planes, will eventually intersect. If they are drawn in 3 dimensions than you can avoid them intersecting. Perhaps the questions is not specific enough?
Is the normal always drawn at 90 degrees from the mirror and lens?
No, the normal is drawn perpendicular to the surface of the mirror or lens at the point where light rays strike. It is used to determine the angle of incidence and reflection or refraction.
What is the maximum number of different rays that can be formed on a line?
Infinitely many. There an infinite number of points on a line and each point can be an end point of two rays.
Can a rays have the same point?
Yes, numerous rays can have the same point.
How many points do opposite rays have in common?
They have one point in common.
The point at which the rays of an angle intersect?
The point at which the rays of an angle intersect is the vertex.
What is the point where light rays meet called?
The point where light rays meet is called the focal point.
