It depends on the definition of "molecule" and "metal".
(Engineers tend to think of metal as things like, steel beams, brass, stainless steel, and things like that. To engineers, "metals" do not form molecules. They form just compounds.)
However, in chemists' view--there are zillions of metal molecules in organometallics. Classic example is butyllithium. Lithium is actually covalently bonded to butane. Also there are many metalloproteins as well.
No, ligands are not complex ions. Ligands are molecules or ions that can donate electrons to form coordinate bonds with a central metal ion to create a coordination complex. In contrast, complex ions are ions formed from a central metal ion bonded to surrounding ligands.
Metals tend to form positive ions also known as cations.
Compounds that can accept an electron pair are known as Lewis acids. These compounds typically have an electron-deficient center, such as metals in metal ions or molecules with incomplete octets. Common examples of Lewis acids include metal ions like Al3+ and molecules like BF3.
Alkali metals are found in group 1 of the periodic table. They will form ions with a 1+ charge. If you meant alkaline earth, they are found in group 2, and will form ions with a 2+ charge.
Metals form cations and non-metals form anions.

Metal oxides typically form hydroxides when dissolved in water due to reaction with water molecules to produce hydroxide ions. These hydroxides can then further dissociate into metal cations and hydroxide ions in solution.
Hydrogen ions can form water molecules (H2O) by combining with hydroxide ions (OH-) or hydronium ions (H3O+).
A metal typically forms ions by losing electrons to achieve a stable electron configuration. Metals tend to form positively charged ions by losing electrons, so they usually have one or more fewer electrons than their original neutral state.
Ionic compounds usually consist of a combination of positively charged metal ions and negatively charged non-metal ions. The metal ions lose electrons to form cations, while the non-metal ions gain electrons to form anions. These oppositely charged ions are attracted to each other in ionic bonds to form the compound.
Atoms combine to form molecules through chemical bonding, where they share or transfer electrons to achieve a stable electron configuration. Ions, which are atoms or molecules that have gained or lost electrons, can also combine to form molecules by attracting to oppositely charged ions through ionic bonding.

Iron is a metal that can form three ions: Fe2+, Fe3+, Fe4+.
Metals ions form solid metal
In sodium chloride (NaCl), there are no metal ions present. Sodium (Na) is a metal cation, and chloride (Cl) is a non-metal anion. When they combine to form NaCl, they do not exist as individual metal ions.
