Arsenic pentaiodide (AsI5) doesn't contain any metal; arsenic is a metalloid and iodine a nonmetal.
arsenic triiodide.
It is a big "V" shape made up of five iodides
The name of this compound is dinitrogen pentasulfide.
Don't know P2I5. PI5 (phosphorus pentaiodide) is more likely but couldn't find anything on that. Maybe this is meant: P2I4 , diphosphorus tetraiodide synthesized from phosphorus triiodide 2 PI3 → P2I4 + I2
PI5
phosphorus pentaoxide or p2o5 dimerises into p4o10
The imaginary compound nitrogen pentaiodide would be NI5 , it would not be an acid- there are no ionisable H atoms. (or a Lewis acid- it has no lone pair.) There is a real compound NI3, a very unstable substance a contact explosive. There is a reported PI5, but that is disputed.

A very dangerous element
diphosphorus pentaiodide
Phosphorous Pentaiodide
Bromine Pentaiodide

NI5 ?IF it exists it would be Nitrogen PentaIodide. It would also be very unstable (i think) so don't go near it.
