The problem is... there are no "standard" parts when it comes to LED display. Every manufacturer has the option, and usually selects it, to build the part any way they please with a pinout of their choosing.
This means... the LED display can be multiplexed to save pins... or not and have many pins... none of use can begin to help until these questions have an answer.
If you have a 5V supply and a 330 ohm resistor... you *should* be able to probe the LED in the package to come up with the manufacturers "layout" for digits 1 -4 and segments A though F. Then find any old example on the web... with Google like... for example: http://www.hobbytronics.co.uk/tutorials-code/arduino-tutorials/arduino-4digit-7segment
If you look here: https://www.sparkfun.com/datasheets/Components/LED/7-Segment/YSD-439AR6B-35.pdf
you might get some ideas about how your part works.
Try it... learn from it... or come back here and ask questions.
But... we are still not able to help you or send you off in the correct direction... because we do not know what you have... or what you want to do with it.
