Can this charger charge one at a time or does it require a set of batteries to charge?

It can charge any of the battery sizes listed, in any quantity or combination desired, up to the max shown. There are 4 total compartments available that can fit either (2) AA, (2) AAA, or (1) C/D. Recharging a 9V would appear to overlap the space in compartment 1.

Any idea how long charged batteries will stay charged without using?

Do you mean, how long charged batteries will stay charged in the charger? If this is what you are asking, the charger seems to discharge the batteries so they don't stay charged if you leave them in the charger. It is however a good fast charger but you will need to remove the batteries immediately after charging.

What all are included in package? Does it also include few batteries with the product?

No batteries are included. One charging station is included, able to charge up to the amount in description one at a time.

Is this a "timer" charger "smart" charger that refills to capacity and then stops?

The charger shuts off when a predetermined value is reached. The charger will not overcharge.
