Yes, you need at least two edges to make a corner. For example, in a cube, the vertex is formed because three edges meet. In a regular square, each side meets to make a corner. If you had only one edge(corner)then it would just go on and on, and since there's not another edge to meet it, it would never make a corner anyway.

Not true. The base has parallel edges.
a triangular pyramid has 6 edges that is true
true
It is triple the number of edges on one base.
True. A cube has 12 edges and 8 vertices.
Yes, it is true that angle 60 degrees has two edges in the angle parts.
true
Yes
True
False. In fact, the opposite is true: all pyramids have an even number of edges.
To make the mean true, the student will need to get 94. To make the mode true, the student will need to get 86. To make the median true, the student will need to get 85. As we can see, the three numbers are not the same number. It is impossible the make the three statements true.
