Two triangles
it's impossible to have a quadrilateral that can't be cut into triangles.
You cannot make four triangles our of a quadrilateral by ONE line through it. One line can give you at most two triangles. Two lines, each running from one vertex of the quadrilateral to the opposite vertex, will give 4 triangles.
A pair of triangles can form a 4 sided quadrilateral
Yes
Two triangles
Infinitely many. Any triangle inside a quadrilateral can be divided into two without affecting the quadrilateral but increasing the number of triangles by 1. And then one of those triangles could be spilt into two and so on - without end.

You can divide a quadrilateral up into as many triangles as you want, but at least two.
Yes, it can always be divided in 2 triangles. This is because every quadrilateral has 2 diagonals. It is these diagonals that divide the quadrilateral into 2 triangles.

A quadrilateral has four sides. Triangles have three sides.

Yes
No. Quadrilateral means "four sides." Triangles have three sides.
