All are true.
ADH (antidiuretic hormone) affects the nephrons in the kidney, so that more water is absorbed into the loop of Henle. Aldosterone causes sodium retention leads to a condition such as DHA.
As you noticed, angiotensin II causes the smooth muscles of arteries and veins contract by reducing the size of the light, reduces the space for the blood that raise blood pressure. It is a very temporary situation.
