The features you have circled are roofed turrets with spires.
A turret is a tower that is part of another structure such as a curtain wall or keep; it is not simply a free standing tower that goes all the way to the ground, it juts out of something else.
If the top of the turret is flat and intended as a fighting platform, it is considered unroofed, although it will typically be equipped with drainage and functionally equivalent to a flat roof. Turrets may have crenelated battlements (there are some crenelations on the bottom-right turret, but they look decorative rather than being something to protect defenders). Turrets can be straight sided or have larger tops supported by corbels, possibly with machicolation.
The spires are essentially just big spikes atop the turrets; they may have lighting rods, weather vanes, radio antennae, flags or other decorative features attached. Or they can be just big spikes - what makes them spires is that they are above the roof of the turrets and pointy.
