Yes all alkalis have an OH- group, however this is not true for bases.
No, not all alkalis contain oxygen and hydrogen. Alkalis are compounds that contain hydroxide ions (OH-) and can include elements like sodium, potassium, or calcium. These alkalis do not always contain both oxygen and hydrogen in their chemical composition.
No, not all alkalis contain hydrogen. Alkalis are a class of compounds that are bases and typically contain hydroxide ions (OH-). Examples include sodium hydroxide (NaOH) and potassium hydroxide (KOH), which do not contain hydrogen on their own.
Some compounds that contain hydrogen and oxygen include water (H2O), hydrogen peroxide (H2O2), and methanol (CH3OH).
Acids contain hydrogen ions (H+), which are responsible for their acidic properties. Alkalis, on the other hand, are bases that contain hydroxide ions (OH-). Hydrogen is not the defining characteristic of alkaline substances.
All alkalis contain the hydroxide ion (OH-). This hydroxide ion is responsible for the characteristic properties of alkalis, such as their ability to neutralize acids and their ability to turn litmus paper blue.

None. Hydrogen, oxygen, and carbon are all elements. Elements do not contain other elements.
No- hydrochloric acid is an acid and is the opposite of an alkali so no alkalis contain it
oxygen and hydrogen

All proteins contain carbon, hydrogen, oxygen and nitrogen. Most of them also contain sulfur, which is found in the standard amino acid residues cysteine and methionine (any given protein might not contain either of these, though it would be unusual).
No because Oxygen is an element and it only contains atoms of Oxygen and nothing else, no Hydrogen at all. A compound of Hydrogen must contain Hydrogen plus something else. Water contains Hydrogen and Oxygen (H2O) so that would be a compound of Hydrogen and oxygen.
Carbon, oxygen, and hydrogen are all nonmetal elements.
They all contain (have) Carbon ,Hydrogen, and Oxygen
