A square is not a solid figure at all. It's a flat figure, with four congruent faces and four congruent angles.
There is no solid figure with only four edges. The smallest solid figure is the tetrahedron, made up of four triangular faces, but it has six edges.
Tetrahedron
A solid figure with five faces is called a pyramid. Specifically, a triangular pyramid, or tetrahedron, has four triangular faces, while a square pyramid has one square base and four triangular faces, totaling five. The pyramid's faces meet at a single point called the apex.
A rhombus is a plane (flat) figure so it has no faces. It has 4 edges and four vertices
A square is not a solid figure at all. It's a flat figure, with four congruent faces and four congruent angles.
The solid figure that has 4 flat surfaces that are triangles is a tetrahedron. A tetrahedron is a polyhedron with four triangular faces, six straight edges, and four vertex corners. Each of the four faces of a tetrahedron is an equilateral triangle, making it a regular polyhedron.
A cuboid.

Four triangular faces.

triangle based pyramids
The answer is a pyramid.
A rhombus is a plane (flat) figure so it has no faces. It has 4 edges and four vertices
triangular prism
A three dimensional figure with polygonal faces is called a polyhedron. Specific names draw from the Latin prefixes. For example a four sided figure is a tetrahedron.
A solid with four faces for maths is a tetrahedron.
