Hey guys, I am just wandering if you can tell me whether these singers are signnging in falsetto or not. Is it more of a mixed voice?

mostly they sing in there modal range which is chest and head voice. you may know it as mixed voice.

GnR sings with reinforced falsetto. and im sure those other bands go into falsetto also
