Is OH found in many proteins?
If you mean the hydroxyl functional group (-OH), then only serine and threonine contain it. However, all amino acids contain one or more carboxylic acid (-COOH) functional groups and they all contain OH as part of that functional group, though the carboxylic acid functional group should be considered a single unit.
Is it true that an Amino functional group is -NH2 but amino acid list it as -NH3 does it matter how many hydrogen atom exists to be a functional group?
The amine group is NH2. But to form an anino acid you also need to have a COOH group. An amino acid contains the highly nucleophilic Nitrogen lone pair. In acid conditions the NH3 is formed from the dissociation of the acid functional group coordinated onto the Nitrogen forming a zwitter ion. HOOCRNH2 +H2O <---> -OOCRNH2 + H3O+ <---> -OOCRNH3+ + H2O
What are amino acids and how many are there?
An amino acid is the basic unit of proteins (including peptides and enzymes). The amino acid molecule is formed by an amino group and a carboxylic group linked to a carbon atom (the alpha carbon), and a side chain group that gives their identity. There are 20 natural or "standard" amino acid molecules. Generally, are grouped according to the polarity of their side chains or "R" groups. According to this classification scheme, there are three major types of amino acids:those with nonpolar groups. Glycine, alanine, valine, leucine, isoleucine, methionine, proline, phenylalanine and tryptophan, form this type of amino acids.those with uncharged polar side chains or R groups. This type is formed by the amino acids serine, threonine, asparagine, glutamine, tyrosine, and cysteine.those with polar side chains. This type is formed by amino acids lysine, arginine, histidine, aspartic acid and glutamic acid.

How many different R-groups are present in 3 different amino acids?
Three, one for each amino acid.

How many amino acids in collagen?
No. Well, yes. It depends on what you mean by "amino acid." Collagen is a protein and is therefore made up of amino acids rather than being an "amino acid" (as the term is generally used) itself. In a strict chemical sense, though, it is in fact an amino acid, as it contains both a carboxylic acid functional group and an amine functional group (at the C-terminal and N-terminal ends of the protein respectively).
What does the general structure of an amino acid look like?
Amino acids are biologically important organic compounds composed of amine (-NH2) and carboxylic acid (-COOH) functional groups, along with a side-chain specific to each amino acid.The key elements of an amino acid are carbon, hydrogen, oxygen, and nitrogen, though other elements are found in the side-chains of certain amino acids.About 500 amino acids are known and can be classified in many ways. Structurally they can be classified according to the functional groups' locations as alpha- (α-), beta- (β-), gamma- (γ-) or delta- (δ-) amino acids; other categories relate to polarity, pH level, and side chain group type (aliphatic, acyclic, aromatic, containing hydroxyl or sulfur, etc.)In the form of proteins, amino acids comprise the second largest component (after water) of human muscles, cells and other tissues.
