'LIL' and 'NE' look like Futura EF: http://new.myfonts.com/fonts/ef/futura/ef-bold/
The 'Y' looks like Devil Breeze: http://www.dafont.com/devil-breeze.font?text=LIL+waYne++A
The 'A' could be Devil Breeze mirrored...
The 'W' looks like Avant Garde Gothic Bold: http://www.fontshop.com/fonts/singles/elsnerflake/avant_garde_gothic_bold_alternative_ot/?&sample_text=W&acs_pt=32
