The arrangement or geometry of the atoms in some molecules is such that one end of the molecule has a positive electrical charge and the other side has a negative charge. If this is the case, the molecule is called a polar molecule, meaning that it has electrical poles. Otherwise, it is called a non-polar molecule.
and coming to your 2nd ques 
among those SF4 is only polar beacuse using the vector drawing its dipole moment are not cancelled out , and all the other 3 are cancelled out . 
HOPE IT CLEARS YOUR DOUBT 
ALL THE BEST ..
