chemistry, how do i draw the lewis structures for these molecules?

i have tried all sorts of ways but keep on geting stuck with atoms which i can't connect, don't have enough non paired valence electrons to join em all up

H$$_{5}$$IO$$_{6}$$

TeF$$_{6}$$

IF$$_{7}$$

SF$$_{4}$$

BrCL$$_{3}$$

SORRY all the numbers are meant to be below the letters, (number of atoms) don't know why it came like that
