if save my data using a computer and upload it to the board can i use it without connecting it to pc and i also need to add fixed 4-5 input command manually on it after disconnecting it from computer is it possible and if possible how?
When you upload a sketch to your Arduino board the code is stored and runs on the microcontroller, not the computer. So the board only needs power and it will run your program.

I'm sure it's possible but we'd need a much clearer explanation of what you're trying to accomplish to say how. The most simple form of input is a button.

OK...
...and i also need to add fixed 4-5 input command manually on it after disconnecting it from computer...
How are you going to add commands after disconnecting it?
You need a computer to write, compile and upload your code.
...is it possible and if possible how?
You could write and debug all the functionality at the outset, then activate or call the desired functions when it’s in-situ without any connection to the computer.
