I don't understand anythingh, someone just please explain these questions to me so that i can do the rest on my own!!!

Please, I supplicate and beg you all, I REALLY NEED HELP ON COMBINATION CIRCUITS (SERIES-PARALLEL) or i'll fail?

or ill fail my test tomrorow.

Combine the resistors into one value where you can. Merge all the resistors into one value, then use that to get the current in the circuit. This will give you the voltages across each leg. Once you have the voltages you can figure the individual currents.
