No, a shape cannot have more than 3 edges meeting at a vertex and simultaneously have a right angled face. A right angled face implies that two edges form a right angle, which is only possible with three edges meeting at a vertex.

No. Only 2 altitudes can intersect at a point. * * * * * True but even they do not meet in the interior. The altitudes of a right angles triangle meet at the right angled vertex. The vertex is at the boundary of the triangle, not in the interior.

A right angle.
A point.
The extreme point is called a vertex.

Two nappes of a right circular cone meet at a point called the vertex.

To find the value of a in a parabola opening up or down subtract the y-value of the parabola at the vertex from the y-value of the point on the parabola that is one unit to the right of the vertex.

Same as it is in any other angle ... the point where the sides of the angle join (or cross).
The intersection will consist of only one point.
