"Thank you, you were very helpful"
Response Details:
The first two are stereoisomers.  The chiral center where the methyl group is located is R in the first molecule and S in the second.

The second two are constitutional isomers.  If you were to draw them out they would be:

  and   
These both have the formula C4H10, but they are clearly different molecules.

The third pair are conformational isomers.  The first one is gauche and the second is anti.

The final pair are identical compounds.  If you were to flip on of the molecules over it would be identical to the other.  This would be easier to see if you have a model set and were to make them both.
