No, Pb is not a transition metal and it has 2 oxidation states
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.
The transition metal element with only one electron in its 5s orbital is copper (Cu).
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).
Silver
Titanium is a transition metal because it has partially filled d orbitals in its electronic configuration. Transition metals are characterized by their ability to form stable colored compounds and exhibit variable oxidation states, which titanium also demonstrates. Additionally, they often have high melting and boiling points, which is the case for titanium.
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

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.
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.
An electron moves from the 4s sublevel to produce a completely filled 3d sublevel. A completely filled sublevel is more stable. Just because it has a filled d sublevel doesn't prevent it from being a transition metal. It has variable valence (1+ and 2+).
Zinc is in oxidation state +2 and oxygen in oxidation state -2. Zinc Oxide itself has not net charge/oxidation state.
The transition metal element with only one electron in its 5s orbital is copper (Cu).
Lead is a main group element, specifically a metal, and not a transition metal or inner transition metal. It belongs to group 14 in the periodic table and is commonly classified as a post-transition metal.
All metals, whether they belong to the transition state or not, will form only positive ions. There are a few metals which are extremely hard to ionize, however, those being the noble metals such as gold and platinum. But if you do manage to ionize them, the ions are positive.
