what is the minimum number of moves required to form the the cross as shown in the figure (black cross) ?
one move means one 90° rotation
according to me it is 4
but i want other's answer also ??

If you start with cross, then technically it takes zero moves.

1 move for the cross. Most crosses are about 6 - 8 moves. One move is a 90 degree or 180 degree rotation, by definition. If you practice the time should be about 3 seconds to make the cross. I can solve the whole cube in 30 seconds, and my average amount of moves for the whole cube (in case you want to know) is about 50 - 60.
which method do u use ?
it will take one move for each non uniform coloured square
I've managed to do it in 5 moves, if you count \(m\) moves as one move.
i think that you mean minimum number of moves in any permutation required to form a cross shown above .. if one move is 90 i think it is going to be 5 or 6 . a good problem let's try to find out what should be no of moves . as we can see the other colours do not matter it is going to be less tedious .
