I have 4 sides. All four of my sides are the same length. I have no right angles. Which shape am I? rectangle
triangle
rhombus

triangle and rectangle have right angles so have to be rhombus

A Rhombus that isn’t a square and a regular tetrahedron both qualify. But your question leaves the possibility of a polygon with more than four sides and one or more sides not being congruent to the four congruent sides. Pentagons can do this easily enough — imagine taking a regular pentagon and moving two of its vertices so that exactly one of its sides shrinks just a little. In fact any polygon of more than four sides can be constructed such that exactly four are congruent and no angles are right
