Quadrilateral ABCD is a rhombus with diagonals AC and BD. if angle M equals 25 find the measures of angles 2 , 3 , 4 and 5

I have no idea where angle M and angles 2,3,and 4 are

Since you make a point of stating there are two diagonals, I can only assume that angle M is intended to be angle CAD or BAC or their opposites on the diagonaly opposite vertex.
If M was intended to be angle BAD or BCD, there would be no need to identify the diagonals.
We also have no idea what angles 1, 2, 3 and 4 are.
If /_CAD is 25º, then /_CAB = /_BCA = /_DCA also = 25º. Angles ABC and ADC = 130º.
If /_ BAD = 25º, then so is /_BCD. Angles ABC and ADC = 155º. 
If the measure of ÐDAB = 50°, and ÐDAC = 20°, what is ÐCAB?
