ohh woww , thanks sir , so you this circuit is suitable for 6v battery ?

and sir what about the value of transistor here in the given circuit diagram above ?
The transistor needs to be rated to handle the load current and power.
Typically it will drop 1 or 2 V. So if you draw 1 A, then the transistor needs to dissipate 1 or 2 W. This requires at least a TO-220 size.
If you draw much more current than that, then you'll need to move up to a TO-3.
You will need to size the bias resistor so as to get 5V at your load.
50 ohms is just the example I chose as the load resistance.
What you plan to supply with 5V, maybe you can use standard rectifier diode to lower voltage for 0,7V its simplest way, or two Schottky diodes with 0,5V each this will give 5V on output. Rectifier diode can handle several amps and much much more. I think for you 6A diode is ok, taking in mind that you use 6V 4,5Ah battery.
i ve so many cicuit designings & many of them have ICs running on 5 volts for a better operation , not less & not much than that as i found there operation successfull by doing so , thats why i need all these cause i am replacing the power source with battery
tpetar sir would you please let me have a simple diagram about what you are explaning ?
hmm kk , so all these things are supportable with a battery power ?????? so may i start my work over it fully ?
