One and two mean the same thing. "GET out of here!" (#1) is commonly used, not "GO..."
Number three is better than number four.
Again, both are correct (five and six, seven and eight). GET is better and more commonly used.
1. Get out of here!
2. Go out of here!
[Can we use both 'get' and 'go'? Are both the same? Or do we have to use 'get' here?]
3. He decided to get over his limitations.
4. He decided to go over his limitations.
[#3 is correct. What about #4? Can we use 'go' instead of 'get' here?]
[When somebody takes a bus...]
5. Get on!
6. Go on!
[#5 is correct. What about #6? They are not the same, are they?]
[When somebody leaves a bus...]
7. Get off!
8. Go off!
[#7 is correct. What about #8? They are not the same, are they?]
