Sodium hydroxide contains sodium, oxygen and hydrogen.
Caustic soda and sodium hydroxide are actually the same compound with different names (sodium hydroxide). When mixed, they will just form a homogeneous mixture of sodium hydroxide without any chemical reaction occurring.
A common name for sodium hydroxide is lye or caustic soda.
NaOH, KOH. caustic soda and caustic potash, sodium and pottasium hydroxide.
Caustic Soda and caustic potash are very common.
They all have a hydroxide. This means they are alkaline (bases)

No they are not. For starters, their names are different. Secondly, in one molecule of sodium chloride (NaCl), there is one atom of sodium to each chloride atom. In sodium hydroxide (NaOH), there is one sodium atom, one oxygen atom, and one hydrogen atom. Sodium chloride is known as salt, and sodium hydroxide is known as lye, or caustic soda.
Sodium chloride is NaCl. Sodium hypochlorite is NaClO.
Chemical names should be capitalized when they are specifically referring to a particular compound or element; for example, "Carbon dioxide" or "Sodium chloride." In general, chemical names are written in lowercase letters when they are used in a more generic sense.

Lye is one of those "common names" that, particularly when combined with adjectives, might mean a couple of different compounds. The canonical lye is sodium hydroxide. However, potassium hydroxide has very similar chemical properties, and I've seen terms like "wood lye" that indicate it's actually the potassium compound instead. "Caustic lye" is a new one on me; both compounds have common names that include the word caustic (caustic soda for sodium hydroxide, caustic potash for potassium hydroxide), so it might be either one. If it's in a recipe for soap or something, it doesn't really matter all that much; as stated earlier, they have very similar properties and either will work.
Both of these would be poisonous to drink, and hence could be marked with the skull and crossbones, although working chemists would just label them with their chemical names.
