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
