Answer 1

Not sure what you want here.

In humans, there are nine amino acids that we cannot make (phenylalanine, valine, threonine, tryptophan, methionine, leucine, isoleucine, lysine and histidine).

There are 6 others that are considered conditionally essential - because their synthesis is limited in some individuals with medical issues (arginine, cysteine, glycine, glutamine, proline and tyrosine).

5 amino acids are dispensable - we can make plenty (alanine, aspartic acid, asparagine, glutamic acid and serine.
