No clue as you did not mention any power requirements for your devices or any other specs for that matter.
In general a 2A charger is just enough to charge a mobile phone these days but not to power additional devices.

ok, 5volt 1amp for mobile and 5volt 1amp for PAM8403(audio amplifier)

That would be on the limit of the supply but could still work if the amp is not at full power and a good sized capacitor is added to the output of the power supply.
But with a phone charger you will need some additional filters as otherwise you get a lot of high frequency noise on the speakers.
