Rotating Game Objects in the Editor

Every game object within a scene listed in the Hierarchy window has a Transform component shown in the Inspector window:
Here, we see the rotation's x, y, and z coordinates (Euler angles). For rotation, think of a rod going along the axis and the object being spun on it. Generally, the x-axis is horizontal, so spinning it moves the object up and down as you are facing it, the y-axis is vertical, so spinning it moves the object left and right, and the z-axis is forward and back, so moving it moves the object clockwise and counter-clockwise.
Since you can change the view of your Scene window and move cameras with their own transform components, the best way to determine an axis is to move the object with the transform vectors and watch the numbers in the component OR change the numbers and watch the object in the Scene View.
You'll notice when you add a new game object, it will often have Euler angles that aren't (0,0,0). Right-click on the Transform component or click the three dots on the right of the component in the Inspector window to get this menu:
Here, Reset resets all the coordinates to (0,0,0) (position and rotation) and 1 x 1 x 1 (scale) or you can click Reset Rotation for just the local rotation of the object in Euler angles.
This will only reset the object's local rotation/Euler angles relative to its parent object. To reset to the game's (or global) rotation of 0,0,0, move the object outside of any parent object in the Hierarchy window, reset the rotation, then put it back where it belongs. This also updates the local reset rotation to whatever new rotation the object has when placed back into the parent object.
Click the Rotate Tool at the top left of the editor.
A quick way to select this is to press the E key on your keyboard.
This will make rotate vectors appear on the selected object in the Scene window:
You can click and drag on the red, green, or blue vectors to spin/rotate the object around the x, y, or z axes respectively. As you do so, you'll notice the numbers changing in the rotation property in its Transform component.
Just like in all components with number properties, you can adjust numbers by clicking and dragging your cursor over the property name. You must first hover over the property name (X, Y, or Z) to make arrows appear around the cursor. Once your cursor moves out of frame, it will reenter on the other side. The numbers should increase and decrease and you should notice the object moving in the Scene View.
In the Transform component, you can also type in the exact angles you need. The object's rotation will match.
