As isosceles triangle.
rhombus
Pentagon
trapezoid
A shape that has 2 right angles, only 1 set of parallel sides, and no lines of symmetry is a right trapezoid (or right-angled trapezium). In this trapezoid, the two non-parallel sides are not equal in length, contributing to the lack of symmetry. The right angles are formed between one of the parallel sides and one of the non-parallel sides.
A plane shape with five sides of equal length, and five equal angles: each of 108 degrees.

The shape that has three lines of symmetry is the equilateral triangle. It also has three angles of equal size and three sides of equal length.
An equallateral triangle ~ID1533681184 Sorry ID1533681184 but and equallateral triangle does not have three lines of SYMMETRY, it has three line segments. ~EEE2
A kite or arrowhead.
A plane shape with five sides of equal length, and five equal angles: each of 108 degrees.
There is no such shape. A 2d shape with 5 sides and all equal angles must be a regular pentagon (or a 5-pointed star if you stretch the definition of "all angles"). And a regular pentagon - or star - has 5 lines of symmetry.
