how to measure the ammeter in a circuit?

ok, I have to calculate two ammeters in a parallel circuit with 4 bulbs.
I can explain how it looks:
it is a parallel as I said before with a battery on top as usual and right next to it on the right is an ammeter that you have to calculate. This is the first line
The second line consists of a bulb on the right and a ammeter on the left the ammeter reading is 1 but between the first two lines on the left there is ammeter which reading is 2.5. that was the second line
the third line is a ammeter on the right which you have to find out and a bulb on the left. that was
the third line
the last line has two bulbs on the right of the line and at the very left there is an ammeter which has a reading of 0.5

The thing you have to find out is the ammeters
just to let you know the answer for the first ammeter which is next to battery reading is 2.5 and the one on the third line is 0.5 the thing is I am trying to find out is how do you do it

Thanks for all the answers
