$\mathrm{XeF}_4$ is square planar in shape due to four bond pairs and two lone pairs that form an octahedral geometry. $\mathrm{ClF}_3$ is Bent T-shaped due to three bond pairs and two lone pairs around the central $\mathrm{Cl}$ atom that together form a trigonal bipyramidal geometry with the two lone pairs occupying the equatorial positions.
$\mathrm{BrF}_5$ is square pyramidal in shape due to five bond pairs and one lone pair around $\mathrm{Br}$ with an octahedral geometry. $\mathrm{IF}_7$ is pentagonal bipyramidal due to seven bond pairs that a range themselves in this position to minimise the repulsion.
