You should study the data sheet, it explains all the instructions and gives examples.
'AH' and 'AL' presumably are register names and independent 8-bit values.
RRF AH, F AH is 0000 0011 before the instruction so rotating it right through the carry flag, bit 7 = whatever was in C, and C becomes what was in Bit 0
The same applies to the AL register but note there is only one carry bit so it may transfer a bit from one register to the next.
We can't predict what the result will be without knowing what was in C at the outset.
