Stars are always in the sky but as the sun shines brightly in the day it can not be seen. They are sometimes not visible at night if it is cloudy or if you are in an area with a lot of light pollution.
Techinally, yes because the sun always shines on the earth. The side of the earth that is dark and is not being shunned by the light is night time. The opposite would be affirmative, day time.
stars are not fixed in the sky,they move at a speed of 20,00,00,000 kms. per hour.
Because Venus, along with Mercury, are inner planets it never appears too far from the sun. In fact Venus never strays more than 47 degrees from the sun. That makes it always appear in the western sky after sunset or in the morning sky in the east at dawn, and that's where our crescent moons always appear.
Clouds occupy the sky for separate reasons. The sky is always blue, except when the sun's elevation is very low (sunrise/sunset) or on very hazy days. It is blue due to the way the atmosphere scatters the sun's light. This has nothing at all to do with why clouds might exist in the sky on a particular day.
No, sometimes it's too close to the Sun (from Earth's perspective, that is) and isn't visible at all.
Essentially yes, the sun always rises in the east and sets in the west.
You will never see Mercury on a dark sky. The reason is that Mercury is the closest planet to the Sun, and so we can only see it shortly before sunrise or shortly after sunset. The sky is always still fairly light.
Yes the sun is always highest in the sky at noon
It is always in the sky but when it is dark on one side of the earth, the sun is up on the other side. So yes, the sun is always up.
The sun and moon are always in the sky, but for half of the time, the earth turns you away from the part of the sky where they are, so that you can't see them. During those times, people on the other side of the earth can see them.
Stars are always in the sky! You just cant see them as well when the sun is shinning.
The sun is always moving in the sky, it never stops. This is the result of the rotation of the Earth, which also never stops.
The sun is always in the sky. But, as the earth rotates, some of the time (at night) your part of the earth is facing away from the so you think it is not in the sky.
The sun always is in the sky. Sometimes you can not see it because it is concealed behind clouds. At night, you will not be able to see the sun from your location, because the earth has rotated away from the sun.
Yes, the sun is always high in the sky in the tropics. At the equator the sun is always higher at noon than it ever gets in Britain.

The sun and the moon are always in the sky but sometimes if it is in the same spot they can make solar or lunar eclipse. http://en.wikipedia.org/wiki/Solar_eclipse

Stars in the night sky always maintain the same distance to what? The sun, the moon, the horizon or the celestial meridian?
