What are the exact meanings of reactive and apparent powers? Do we say they are supplied or consumed?
To answer your questions, it require a little bit of basic theory.
When working with ac quantities, 2 things were observed:

When load is connected to the supply source, some power is consumed by circuit and electrical energy is converted to heat, rotating and other types of energy
But on closer inspection, it was seen that voltage and current profile were higher than the load required(resistive part of the load)

So in short, real power is actual energy being consumed by the load resistive part and transferred to another form where as, reactive energy is the power flow between energy storing elements(inductor, capacitor) and supply source, that means, in a cycle, some energy flows from the supply and gets stored in inductor/capacitor and then during rest of the part of the cycle, energy is given back to the source. So the net balance arrives at 0 energy in average sense.
Relevance of reactive power: Since both power flows in the circuit, the rms quantity actually represents in a correct way of the rating of voltage and current being supplied from source to load(Although reactive power does not contribute to anything). That is why we want the reactive power requirement of the load to be as low as possible(or some workaround). Higher the reactive power, higher the in-between components ratings(Cost increases).
Apparant power gives you a total of energy being supplied from source(Real + Reactive).
I think by looking into this theory, you will be able to answer your questions
