I would like to convert 6 leds to 7 segment display. What is the best way to
do it? The way it works right now that LED's lit up in a continuous style
(for example: 1st will light up the 1st LED, 2nd will light up the 1st and
2nd LED, 3rd will light up the 1st 2nd and 3rd LED's, etc. etc) I got 7
negative inputs and 1 positive signal as you can see from the picture that
every led get grounded to lit up.

What is it you are trying to achieve? Do you want to have the 7-segment
display indicate the numbers 1,2,3, etc or just light up the segments in
order? If you want to indicate the numbers, you need a decimal-to-seven
segment priority encoder.

On the assumption that you may be doing this for a car battery indicator,
look at:

It'll give you ideas anyway if this isn't exactly the application.
