in a VSEPR shape with more than one angle size, i.e. seesaw, would all the angles decrease because of the lone pair (so angles are <90, <120, <180)? or do just the angles next to the lone pair bonding region decrease?
The lone pair pushes the other regions of electron density closer to each other, making the bond angles smaller. but we can only do this qualitatively, we don't know exactly how much they change.
@Leila: The shape of AX2E is bent. The bond angles are 120 degrees. For AX2E2 it is still bent, but the bond angles are 109.5 degrees since the two lone pairs push the two atoms further away from them therefore decreasing the angle.

the bond angles of an octahedral are 90. Therefore, as there is a lone pair in AX5E, the shape is a square pyramidal and the resulting bond angles are <90
