No, Pb is not a transition metal and it has 2 oxidation states
Metals can be solid or liquid. Through Melting Phase Transition, the solid metal will change its state from solid to liquid. Through Freezing Phase Transition, the liquid metal will change its state from liquid to solid.
Scandium is a metal because it is in the transition metals section of the Periodic Table. The nonmetals are located near the right of the periodic table and the metalloids are right next to them between the metal and nonmetals. There are only few metalloids.

Yes Silver (Ag) has atomic number 47. It is in column 11 (IB) Those elements in the middle of the chart, as well as the Lanthanides and Actinides are considered Transition Elements (metals).
Preferably in modern nomenclature, by capital "Roman numerals" within parentheses immediately following the name of a transition metal element cation in a chemical compound. For transition metal elements that have only two common cationic oxidation states, the oxidation states can alternatively be indicated by the suffix "ic" for the more positive oxidation state and "ous" for the less positive ones. Examples are "ferric" for "iron (III)" and "ferrous" for "iron (II)". If the transition metal is in an anion, the most common indication is with suffixes and prefixes, but the appended oxidation state in parentheses can also be used. Details may be different for different transition metals and should be sought in an authoritative reference source.

Zinc commonly exists in compounds in the +2 oxidation state only, and as a metal with an oxidation state of 0.0, 1 and 2 oxidation states
Vanadium is an example of d-block element or transition metal. It is a hard, silvery gray, ductile and malleable transition metal. The element is found only in chemically combined form in nature, but once isolated artificially, the formation of an oxide layer stabilizes the free metal somewhat against further oxidation.
They are used to tell you which oxidation state the particular metal has when bonding to the non-metal. This is only done when the oxidation state can be more than one value.
Zinc is in oxidation state +2 and oxygen in oxidation state -2. Zinc Oxide itself has not net charge/oxidation state.
Metals can be solid or liquid. Through Melting Phase Transition, the solid metal will change its state from solid to liquid. Through Freezing Phase Transition, the liquid metal will change its state from liquid to solid.
Generally, metals attain positive oxidation numbers only. Non metals can have either positive or negative oxidation states. If an oxidation number is a negative value, it can be deduced that it's a non metal element.

Under normal conditions, +2 is cadmium's only positive oxidation state.
