Well, I'm creating the project Keyboard Instrument from the starter kit..But without getting the starter kit (not available in my country)..And i got a problem in the buzzer..Here are the available buzzers in my country:
9V Small Buzzer
6V Small Buzzer
I'm using a 9V battery (Using a battery holder with a DC male end).
So which will be better?

Either one. Both will require a transistor to sink current thru if powered from 6V or 9V.
The 6V unit may work at 5V, but at a quieter level.
The 9V unit would be more convenient, no fooling around creating 6V supply to power it.
I don't know how to relate "5.00L.E." to USD, but if it's not much, get one of each and experiment.
Get a simple NPN transistor,"0.25L.E.", and a 180 ohm base current limit resistor. The kind of parts that would be in the starter kit.

If you want to build an "instrument" that can play "different tones": NONE of them.
Those both are "buzzers" that create a sound when connected to power.
Frequency 4,100Hz as far as I see.
To create different tones (frequencies) you'd need either a small speaker with an impedance as high as possible (i.e. 5cm /2inch speaker with 16 Ohms impedance) and a 10µF capacitor for coupling.
Or a "piezo speaker".
