These letters (when capital) are the ones drawn with only straight lines. The other letters (again, when capital) are drawn with curves.
If you're talking about straight lines (not curves) the answer is one.
All circles are plane curves drawn by a point that rotates 360 degrees at a constant distance from a fixed point.
If you are talking about straight lines, the answer is NONE, because that is what noncollinear means. If curves are allowed, then the answer is infinitely many.

Two tangents can be drawn from a point outside a circle to the circle. The answer for other curves depends on the curve.

They aren't. French curves were handmade to make smooth curves on hand-drawn drawings. They had no real formulae and every maker made many with smaller and larger radii in all sorts of sizes. Big ones were used for ships hull curves. There are ways of making similar curves with any CAD program, and that's how it's done today.
It is object (lines and curves) or shape you can drawn or use existing pre-defined vector shapes from Custom Shapes in Toolbox.

Lines of equal summer temperature are Isothere. Lines of equal general temperature are Isotherm
