Rohmbus is a four sided figure (quadrilateral) that is made up of two equilateral triangles
It would depend on the triangles, but assuming they were equilateral or isosceles, a trapezoid if alternated in a line.
Infinitely many. When you have one equilateral triangle, you can join up the midpoints of its sides to make into 4 more equilateral triangles. And then each one of those can be split up and so on.
It has a four sided square base and four other triangular sides reaching up to an apex. It is a pentahedron. If the four triangles are equilateral, it is known as a Johnson solid, and six of the pyramids will fit together to make an exact cube. If the four triangles are not equilateral, then they are isosceles.
Put the triangles in a line alternately pointing up and down.

Many different types, but mostly equilateral triangles.

Four equilateral triangles make up another equilateral triangle.

Yes, as long as the equilateral triangles are all of the same dimensions. One can be he base while the other three will have one edge on the base and he other two connecting to another triangle with the three standing up triangles meeting at one point.
