Since the original circuit has two loops, then we will need to assign two loop

 
Since the original circuit has two loops, then we will need to assign two loop currents in each going clockwise.
You will write the characteristic equations for each loop by applying KVL. 
You will solve the simultaneous equations to calculate I1 and I2. And then calculate the current in each resistor.
You will need to connect your measuring instruments as shown below to measure current in each resistor and verify your calculations.
