a) the least electronegative is H, followed by I, Br and Cl.

b) (put the arrow that is indicated in your question since I can't draw it perfectly here, but I can indicated the direction of the arrow)

(+) H ---->  I (-)

(+) H ---->  Br (-)

(+) H ---->  Cl (-)

c) since Cl is more electronegative - the molecule HCl is more polar (plus dipole moment data indicate so), followed by HBr and then HI (the least polar).
