if you want to make three things happen, like 3 lights flashing like

- - 0
- 0 -
0 - -

then you need more than a 555 timer.

you can use a 4017 decade counter.

if you just want all three to flash at the same time, like this:
0 0 0
- - -
0 0 0

then you need only a 555 timer setup in astable mode. search for some of my old posts, i've had this explained several times :)

if you have any questions feel free to ask.
