I believe that is an isosceles triangle.
An EQUILATERAL triangle has all three sides the same length. An ISOSCELES triangle has two sides with the same length. A SCALENE triangle has all three sides different lengths.
There are two types of triangle: 1. Scalene triangle - no sides have the same length 2. Isosceles triangle - at least two sides have the same length a. Equilateral triangle - an isosceles triangle with 3 sides the same length.

A rhombus, I believe.

An "isosceles" triangle has two sides the same length (and two angles the same).

It is an isosceles triangle when two of its three sides are of the same length.
If only two sides of a triangle are the same length it is an isosceles triangle. If all three sides are the same length it is an equilateral triangle.
An isosceles triangle has two sides of the same length.
Hexagons have six sides, not four. Any number of them can be of the same length.
A kite or arrowhead.
Not necessarily, but the two non parallel sides could be the same length.
