Over all Questions

hi Camille, sorry i am asking way to many questions but weak chord compression produces breathier sound, is falsetto also due to weak chord compression?

can you tell a diffrence between falsetto and head voice some other way if you can't by listening?

what does supported range mean? please explain. (anatomically would be better) can you expand your supported range?

what does reasonance mean?

what is differnce between supported notes and reasonance notes?

after practicing falsetto, i kind also start talk in this sort of breathy or breathier tone than my actually natural voice even if i dont want to?

does whistle register for men also start after D6?

my vocal fry, i checked on many tuning apps and websites but i go as low as B1 then suddenly i skip a few notes and go up to Bb2 to C3 up to about F4 but i can't hit those missing notes with vocal fry and the fry itself is very controllable? 

Yes, falsetto uses less compression than head voice! Falsetto may feel lighter than head voice, physically. 

I don't know what is meant by "supported range"!

Resonance refers to the vibrations within the vocal tract. See here for a live lesson on resonance and tone. 

It makes sense that your speaking voice is breathy after singing in falsetto for a while, since you've just been training in that mode!

Whistle for men can start as low as A5 - it just depends on the singer!

I'm not sure how to help without hearing you, but for most styles of music we don't need to have a huge vocal fry range!

thank u.

how can i make sure i sing in my natural voice like when i sing i try to sing in my natural voice but then i suddenly starts sounding different sometimes i feel like because the song uses falsetto or head voice so that the only thing changing is me shifting to head voice or falsetto but sometimes it actually sound like my voice is coping the singers timbre or tone and i know that because after i do that my voice becomes super squeaky or hoarse or tired like i cant even hit D4 without wobbling

I encourage you to choose songs that feel like an easy fit for your voice (especially at first). That way, you won't be straining to imitate a singer whose tone or range is very different from your own. 

You can also try singing the melody on a neutral syllable (like MUH or BAH).
