I have certain power adapters used for printers and cellphone charging. Can i use them for creating LED lighting? Answered

The available adapters are 240vac to : (i) 5V/1000mA DC, (ii) 9V/1A DC, (iii) 15V/1A DC, (iv) 3.7V/350mA DC, (v) 3.11V/850mA DC, 5V/700mADC,
Please give me the details of circuits, how many while LEDs can be used and specigfications of resistors to be used, if any. Thank you.
