What stream of charged particles that escape through holes in the sun's corona is called?

It is called the corona of the sun.


Why don't light rays that stream through an ope window into a darkened room spread evenly through the entire room?

Why should they? As you said, the light "streams" or travels in straight lines, called rays, from the source, which is the Sun about 93,000,000 miles away, through your window to maybe a distance of twenty feet (if the darkened room is large). As the rays enter the window, the only thing that deviates their path is scattering off whatever dust particles and aerosols are in the air. This you can see as a "sun beam" in a darkened room, but only because the light has been scattered into your eyes by those minute particles. If the air is clear and dry, and you are standing to one side of the rays entering the window, you see... nothing! The light entering the window has to reflect or scatter off of something to enter your eyes. On the other hand, try this on an overcast day where the light is coming into the window from all different angles. The light from the window WILL be spread (more or less) evenly through the room! However, with direct sunlight, usually the light hits the floor, or a wall, and reflects from those surfaces in all directions (diffuse reflection), partially illuminating the entire room, but also absorbing some of the light. If everything is painted black, most of the light will be absorbed and the room will appear to remain dark. Some of the light rays may also hit a mirror (specular reflection), which re-directs the light rays to the floor, a wall, or the ceiling, again partially illuminating the room with diffuse reflection from those surfaces. Light is invisible until it enters your eye and is perceived on your retina. Which is why you can't see the rays from a laser beam pointer unless there is dust, smoke, or fog in the air to scatter the rays into your eye. Except in movies and on TV where the "special effects" team makes sure you can "see" those invisible laser beams.

What stops electricity from passing through?

A sheet of aluminum foil will provide shielding against a stream of electrons. Note that a stream of electrons will have trouble getting through air itself. That's because electrons have extremely small mass (compared to atoms), and because the electrons in a stream would have to "break through" all the electrons defining the volume of all the atoms in the air through which they are moving.Note that a stream of electrons in this case is notelectric current flow as we normally know it. We're talking about as stream of electrons as might emerge from an "electron gun" of some kind. There are real electron guns in cathode ray tubes (CRTs), and this is the source of the beam. But that beam wouldn't fair well trying to move through air, so the tube is highly evacuated. Electrons can be stopped quite readily, though if they are highly accelerated and strike metal targets, X-rays could easily result.
