It means they are moving away from us.
red shift is a distance and galaxies are planets. galaxies are also chocolate bars and red shift is not. thanks for your time. now go use your own knowledge and stop using google you gimps.
It tells us that most galaxies are moving away from us.
Generally, the galaxies that are further away will have the larger red shifts.

the universe is changing by red shift because when red shift occurs it means that galaxies and stars are moving away from us. this means that the whole universe must be expanding.

When galaxies move away from us, the waves of light stretch out- ie, they become redder. The greater the red shift, the faster the galaxies are moving away from us.

Galaxies that are moving away from the sun are red shifted, that is the light from them looks more red to us that it is when it is emitted. This is due to the speed of the galaxy moving away from which in effect stretches out the wavelengths of the light. Red shift is not the method by which galaxies move away from the sun, rather, it is a consequence of it.
The Hubble telescope did not discover that there is a red shift in the spectra of Galaxies. The telescope is named after the American astronomer, Edwin Hubble, who discovered the phenomenon in the 1920s.
The Red Shift or Doppler effect

That is called a red shift or a Doppler shift.

The Big Bang theory predicts an expanding universe. The red shift, being the Doppler effect of light when something is receding from you, confirms this because when looking at galaxies the light emitted from them is red shifted. The farther away galaxies have a higher red shift, confirming that all galaxies are moving away from each other, not just the Milky Way (i.e. the universe is expanding).
The red shift depends on the relative motion of the emitting source and receiving detector. Hydrogen per se has no red shift. There is hydrogen with great red shift (in stars in galaxies far away that are moving rapidly away from us).
