In physics, a vector is basically anything you can measure (or imagine) that has both a magnitude (something you can express with a number), and a direction. An electric field has both; at any point in space, a unit charge will experience a force (which is in itself a vector). The electric field at any point can be understood as the electric force per unit charge.
No, electric potential is a scalar quantity, not a vector quantity.
No, the velocity vector of a charged particle is not affected by the electric field if it is perpendicular to the field. The electric force acting on the particle is zero in this case because the force is given by the product of charge and the component of electric field parallel to the velocity vector.
Light is characterized by its electric vector because its interactions with matter are primarily through the electric field. The magnetic field of light comes into play when dealing with certain materials or under specific conditions, such as in radio waves or at high frequencies, but in general, the electric field of light is more prominent in its interactions with matter.
Scalar
Electric flux is a scalar quantity, as it represents the amount of electric field passing through a given area. It does not have a direction associated with it, unlike vector quantities.

Direction of the electric field vector is the direction of the force experienced by a charged particle in an external electric field.
Scaler. The electric field is its vector counterpart.

Examples of vector quantity are displacement, velocity, acceleration, momentum, force, E-filed, B-field, torque, energy, etc.

Yes, it is.
From an electric field vector at one point, you can determine the direction of the electrostatic force on a test charge of known sign at that point. You can also determine the magnitude of the electrostatic force exerted per unit charge on a test charge at that point.
