1, Shouldn't this be parts of the sound articulation system? Otherwise, it'd literally be 'Lungs' and 'Mouth, Vocal tracts', respectively
If not, then Labio (Lips), Dental (Teeth), Alveolar ridge, Hard Palate, Soft palate.. and the part that is responsible for the 'glottal' and 'velar' sounds

2, Back of the mouth, around the tonsils
Back of the mouth, in front of the tonsils

3, Contracting and relaxing vocal cords

I have never heard of any of these questions, so my answers are probably irrelevant or too broad.. sorry :\
