#1 & #5 are the same. #3 & #6 are the same also though I'd rather not guess as to what they are.
#2 looks to be E.In. Rosewood.
#4 looks to be Jatoba (Brazilian Cherry).
I don't think #1 are the same i think its the finish crackling thats making it look like #1 which I believe is oak.
None of these cues are oak. 100%
