The problem with this question is that bond angles will depend on which molecules are being referred to.

PBr2 and PClBr are not compounds they are transient molecules.

In VSEPR terms they are odd electron molecules with 7 electrons in the outer shell they will be bent. I do not believe that bond angles are known.

P2Cl4 - the molecule is trans Cl2P-PCl2- I don't know if bond angles have been determined

P2Br4 is not well characterised.

In PBr3 the Br-P-Br angle is 101 o

In PBr5 the solid is actually PBr4+ Br- PBr4+ is tetrahdral with 109.5o angle

Mixed halides PClBr2 and PCl2Br are known. I can't find the bond angles for these. VSEPR predicts a trigonal pyramidal shape - bearing in mind that the bond angles in PBr3 and PCl3 are 100 o and 101 o respectively I think a prediction of around 100-101 o would be reasonable for the Cl-P-Br angle.
