Not sure
but I think
for INDIRECT its 2 Memory accesses= 1 as EA refernce to get the EA and 2nd as Operand fetch to get the actual operand from EA

in INDEX and BASE - its same as direct so 1 in each
someone please confirm..

register indirect mode > 2 //1 for instruction + 1 for operand address

index register mode    > 1 // 1 for instruction

base register mode     > 1 // 1 for instruction
