A square.
Opposite sides will be of equal length, but touching lengths may differ. No, not necessarily - The only time it has equal angles is when it is a square or a rectangle.
A rhombus always has four equal sides and two pairs of parallel sides. It may have either two obtuse angles or no obtuse angles. If it has no obtuse angles, then that particular rhombus also qualifies as a square.
An Equilateral has 3 equal sides and 3 equal angles A scalene triangle has no equal angles and no equal sides.
A rhombus has four equal sides but not necessarily equal angles. but tht is all i got

Yes. The two angles on either side of the reflex angle are normally equal.
Yes. By definition a square has four equal sides and four 90º angles, so any two adjacent sides are perpendicular.
Six equal angles and six equal sides means you've got a hexagon there.
Squares
If the rhombus is a square, it has 4 right angles. otherwise, no.
it has got two pairs of adjacent sides of equal length and one pair of equal sides
