Phosphorus will form the phosphide (P3-) ion.
The ion of phosphorous (P) is P^3- and is referred to as phosphide.
There are none. The phosphite ion PO33- ion is theoretical. When you try to form compounds containing it you actually get HPO32- where the H atom is bonded directly to phosphorus. Historically these compounds are confusingly called phosphites, and the modern name is phosphonate.
Pb is the elemental symbol for lead. In this form, lead is neither a cation or an anion - it is neutral. However, lead acts like a metal and when it becomes an ion, it tends to form a cation by giving up electrons and becoming positively charged.
P3- This is the phosphide ion, but it is not stable in water, only with 3H in PH3 (comparable with ammonia NH3) or with some metal ions (eg. Li3P, Ca3P2, AlP) it is found as pure substance. There are also other form with negatively charged phosphorous in it.
I suspect you are on about Phosphorous
Also phosphorous is the ion (PO3)3-.
The phosphide ion, meaning phosphorous by itself not bound up in a poly-atomic ion, has a charge of -3 in ionic compounds.
The charge of Phosphorous (P) as an ion is -3.

HPO3 is a chemical formula, which is called "metaphosphoric acid," consisting of a hydrogen, phosphorous, and three oxygen atoms to form an ion by binary covalent bonding.
There are none. The phosphite ion PO33- ion is theoretical. When you try to form compounds containing it you actually get HPO32- where the H atom is bonded directly to phosphorus. Historically these compounds are confusingly called phosphites, and the modern name is phosphonate.
P3-
The phosphide ion, with formula P-3.
