Galilean space-time renounces that use of co-ordinate systems such as x3 and t1 because comparing two space-time co-ordinates such as x3=1,2,3, t1=1 and x3=1,2,3,t1=10 says you are looking at the same point in space 9 seconds apart. This is thought to be naive. But in special relativity, time is relative. And because there is no absolute space, would the notion of relative/personal space exist? As in, a moving co-ordinate system has its own space despite its motion.

No it doesn't. There is no trouble labeling coordinates that way in Newtonian mechanics.

I didn't understand any of that.
