The two foci are necessary to define the location of an ellipse, but the shape depends on the eccentricity, which is related to the lengths of the two axes.

What two points define the shape of an ellipse
It is simply an elongated circle, possibly an oval but NOT an ellipse. It is not an ellipse because it has two straight sections. An ellipse is curved at all points along its perimeter.
the foci (2 focal points) and the distance between the vertices.
an ellipse.
The major axis is the line that joins the two foci (focuses) of the ellipse. If all you have is a picture of an ellipse and you don't know where the foci are, you can still find the major axis in a few seconds: It's the longest possible line that you can draw completely inside the ellipse, and it's the line straight across the ellipse between the two opposite "points of the egg".
a regular oval shape, traced by a point moving in a plane so that the sum of its distances from two other points (the foci) is constant, or resulting when a cone is cut by an oblique plane that does not intersect the base.
The two fixed points are the foci but these do not define the shape of the ellipse. You also need to know the eccentricity.
There are two points: the foci.
Ellipse.
What are two points inside a ellipse
No there can never be a single point. But yes there are two such points called foci( each called focus) that helps to define an ellipse. An ellipse can then be defined as a curve which is actually the locus of all points in a plane,the sum of whose distances from two fixed points (the foci) is a given(positive)constant . This is further expressed mathematically to obtain the equation of an ellipse.
An ellipse? The shape described is not an exactly describable geometric shape, (), and as far as I know there is no name for it.
Ellipse is a term for an oval. Specifically it is a shape where the sum of the distance of every point on the ellipse to two points, called the foci, is equal.
An ellipse, a hyperbola.
An ellipse have two focal points.
The two central points of an ellipse are officially known as the foci (plural of focus).
