Adjacent angles share a ray.
When two angles share a common vertex and a common ray, they are called adjacent angles. Adjacent angles are positioned next to each other and do not overlap. They can be part of a larger geometric figure, such as a triangle or a polygon.

adjacent angles mean next to, need a common ray or vertex.

adjacent angle
Adjacent angles share a vertex and one ray, while any two angles that don't share both those things are nonadjacent.
adjacent
Yes (supposing that by side you mean ray...angles don't have sides because they are 2D, not 3D.) If you have a point and you draw four random rays from that point, that only meat at that point, then you would have created four angles. The two angles on opposite sides of the point will share a vertex, but not a RAY.

It meets all definitions I can find, and it would seem that a straight angle can be adjacent. Definition: (1) Two angles that share a common side and a common vertex, but do not overlap. (2) An adjacent angle is either of two angles having a common side and a common vertex. Adjacent angles are angles that have a common ray coming out of the vertex going between two other rays. Another way of saying this is that adjacent angles are next to one another, side by side or adjacent. (Hence the name) It is an angle next to another one in a polygon.
