A pyramid could be constructed from 4 or more triangles.
A dodecagon is a 12 sided shape made from 10 triangles
An heptagon which is a 7 sided shape made from 5 triangles
Yes.
It would depend on the triangles, but assuming they were equilateral or isosceles, a trapezoid if alternated in a line.

Absolutely. Any two congruent right triangles will form a rectangle, and if the right triangles are isosceles right triangles, they will form a square.
the shape that can make two smaller triangles is parallelogram.
