A rhombus.
It could be a trapezoid having 2 right angles, an obtuse angle and an acute angle
A regular polygon of n sides (where n > 4) has n obtuse angles. Since there is no limit to the number of sides that a polygon can have, there can be no limit to the number of obtuse angles in a shape.
Irregular Rhombus
A trapezoid can have 2 right angles, 1 acute angle and 1 obtuse angle that all add up to 360 degrees and it has a pair of parallel sides.
no
A rhombus.
a scalene triangle, an obtuse triangle, a right angle.
If one angle is a right angle, it is a right triangle. If one angle is an obtuse angle, it is an obtuse triangle. If there are no right nor obtuse angle then it is an acute triangle.

Four SIdes
A regular polygon of n sides (where n > 4) has n obtuse angles. Since there is no limit to the number of sides that a polygon can have, there can be no limit to the number of obtuse angles in a shape.
Irregular Rhombus
A trapezoid can have 2 right angles, 1 acute angle and 1 obtuse angle that all add up to 360 degrees and it has a pair of parallel sides.
The shape you are describing is a trapezoid. A trapezoid is a quadrilateral with at least one pair of parallel sides. It can have two right angles, but it does not have any lines of symmetry due to its asymmetrical nature.
