An irregular hexagon
Any shape with more than 3 sides can have two pairs of equal sides and no right angles. If it only has 4 sides in total and isn't a parallelogram, then it's a trapezoid.
An equilateral triangle has 3 equal sides and 3 equal interior angles (of 60o.)
A triangle has 3 sides, 3 angles ( hence the name triangle ) and three kinds of common types ( Right, isosceles, and scalene. )

A seven sided shape is a heptagon.
An irregular hexagon
If the question is about a plane shape with exactly 3 right angles it could be an irregular polygon of 5 or more sides. If the shape can have more than 3 right angles then a square or rectangle are also possible. Finally, in 3 or more dimensions, a polyhedron with any number of faces can have 3 or more right angles.

No polygon can have less than 3 angles. It would be a triangle with 3 sides but that has 3 angles.
