The "Rocker Tattoo" on his upper left arm was paid for by Chris Weber
Below that there's the "Victory or Death" tattoo.The motto of the 32nd Armored Regiment of the U.S. Army.One of Axl's favourite mottos from what I know.
On his upper right arm there's the "Black Rose" tattoo.Thin Lizzy's album cover.Thin Lizzy is one of Axl's favourite bands.
Below this tattoo there's the tattoo of a woman with black hair who is said to be Michelle(the girl that Axl used to date and the woman he wrote the song "Michelle" for).
On his right forearm there's the Appetite Cross tattoo.He got it at the Sunset Strip Tattoo by Robert Benedetti.The tattoo has the skulls of all the past GN'R members on it.
All these tattoos were done around 1984-85.As you can see in some Hollywood Rose photos(Axl's band before GN'R) Axl has no tattoos so I'm guessing that he had his tattoos done when GN'R were formed.
Now,from 1994 to 2001 he had three more tattoos done.One on each leg and the third one on his left wrist.The one on his wrist is a skull chain but unfortunately I'm not sure about the ones on his legs cause there isn't a clear pic of them.
Hope the info is enough and I really hope that I helped you.If you have more questions don't hesitate to ask me again!
