singing high

hi can i know is it good if i can sing f5 by mixed voice and can touch g5 a bit too

Yes, that's quite high! Singing up F5 and G5 in mix will set you up well to sing songs by singers like Ariana Grande, Demi Lovato, Beyonce and Jessie J. 

well can i know like when we sing by mix voice do we feel bit light more than we sing from chest

Yes, your mix will still feel connected and strong, but not as heavy as chest voice!

can you tell me actually how mix voice and head voice sound like with an example....im bit confused..........does mix voice sound a bit nasal..........
