Yes, you can draw a circle through the four points of a trapezoid, because the four points of the trapezoid can be equidistant from one point, making that distance the radius.
You can't. It is impossible to have five equidistant points on a sphere, with the exception of trivial cases (i.e. where the radius is 0 or when one or more points are equal).
The set of all points in the plane equidistant from one point in the plane is named a parabola.

To find a point equidistant from three other points, construct perpendicular bisectors for two of the segments formed from three points. Note: this will be the center of the circle that has all three points on it's circumference. Three points, not in a straight line, form three pairs of points with each pair defining a different line. Take any pair of points and draw the perpendicular bisector of the line joining them. Repeat for one of the other pairs. These two perpendicular bisectors will meet at the point which is equidistant from all three points - the circumcenter of the triangle formed by the three points.
None. If a point is 2 units from 'A' and equidistant from 'A' and 'B', then it also has to be2 units from 'B'.But the shortest distance between 'A' and 'B' is 6 units, and the point on that line that's equidistantfrom both of them is the point in the middle, which is 3 units from each.So a point equidistant from 'A' and 'B' must be 3 or more units from each one. 2 units won't do it.

The equidistant point of a straight line is the middle. Measure the distance from one end to the other and half it.
Yes, it is true. In a perfect geometric sphere, all points on its surface are equidistant from its center. This property is one of the defining characteristics of a sphere.
