pH3. It is more acidic
PH5 does not exist. If it did, the bonds would possible be polar as there is an electrnegativivty difference between P and H. PH3 does exist and will have bond polarity.
Yes
PH5 doesn't actually exist as a stable molecule. However, if one imagines it to have the same geometry as PF5 (namely trigonal bipyramidal), then by symmetry PH5 would be non-polar.
It will go down by 1 or 2 i think because water is pH 7 and pH7-pH5=2
This compound could possibly exist, but it would be very unstable towards decomposition to PH3 and H2. One could propose either an ionic (PH4+H-) or covalent structure for this compound. The covalent structure would involve an expanded valence shell involving d2sp3 hybrid orbitals. For phosphorus, valence shell expansion is usually favored by bonding to electronegative elements such as halogens. Since hydrogen is of similar electronegativity to phosphorus, this covalent structure would not be favored. Concerning the possible ionic structure, the hydrogen atoms bonded to PH4+ have some protic character. Therefore they would readily react with the hydride ion to form H2. If PH5 could be made, it would be stable only at very low temperatures under very high pressures.

Phosphorus has two valencies 3 and 5. 3 - in compounds such as PH3, PCl3, P4O6 5 - PCl5, P4O10 In terms of cordination, the "count" of all the atoms around a P atom it can have 2- 9 atoms around it. Examples are below:- 2 - in OPCH2 3 - in PH3 4 - in PO43- 5 - in PF5 6 - in PF6- And in some phosphides where there bond is more ionic even higher coordination numbers are known:- 7 - in crystals of Ta2P 8 - in crystals of Hf2P 9 - Ti3P
