No. A red shift indicates that the object is moving away from the earth.
Red shift occurs when an object moves away from the observer. So as you are on Earth, it is when objects move away from Earth. (Blue shift as it moves closer.) A star's red shift could be due to losing energy to gravity.

The red shift shows the velocity with which an object is moving away from the earth. The red shift of an object is correlated to its distance from the earth and so it is also a measure of the distance.
Yes. If the star is moving away from the Earth, its spectral lines will shift towards the red end of the spectrum. If it is moving towards the Earth, its spectral lines will shift towards the violet end of the spectrum. This is due to Doppler effect.
It means they are moving away from us.

Since the stars are not stationary in relation to earth, i.e. they are moving towards or away from the Earth, their light will be subject to Redshift (if they are moving away) or Blueshift (if they are getting closer). The faster they are changing distance, the greater the shift in wavelength.
Most galaxies have a red shift away from us - meaning they are moving away from us. However, the Andromeda galaxy has a blue shift, which means it is moving towards us. In about 2.5 billion years time, the two galaxies will merge.

It shows how galaxies are moving in relation to Earth.
Red shift means that other objects in the universe are moving away and blue shift means they are moving toward you. This helps to tell where these objects came from, and this knowledge helps predict where they are going to.
No shift under those conditions.
The red shift shows the velocity with which an object is moving away from the earth. The red shift of an object is correlated to its distance from the earth and so it is also a measure of the distance.
A blue-shift means an object is moving towards us, a red-shift means it is moving away from us. Blue-shift and red-shift are changes in frequency of the light we receive, due to the relative movement. This is called the Doppler effect.
Yes. If the star is moving away from the Earth, its spectral lines will shift towards the red end of the spectrum. If it is moving towards the Earth, its spectral lines will shift towards the violet end of the spectrum. This is due to Doppler effect.
