The number of possible genotypes is typically higher than the number of observable phenotypes because multiple genotypes can result in the same phenotype due to genetic variations, interactions, and environmental factors. Different combinations of genotypes and environmental influences can lead to similar outward traits, resulting in fewer distinct phenotypes than genotypes.

I think you have the question backwards, "Why isn't it possible to have more phenotypes than genotypes?" There are always more or an equal number of genotypes relative to phenotypes. The phenotype for a simple dominant/recessive interaction (for example) T for tall and t for short where TT is tall, Tt is tall and tt is short has three genotypes and two phenotypes. If T and t are co-dominant then TT would be tall, Tt would be intermediate and tt would be short. (Three phenotypes and three genotypes.)
Genotypes are not created by phenotypes, they are the alleles/genes of the organism. Genotypes (in combination with environment) produce phenotypes. It would be expected that the genotypes Bb and BB would produce the phenotype B.
Indirectly, yes it does. But it can only act on genotypes through their phenotypes.
The diagram can be used to predict the genotypes and phenotypes of offspring by following the inheritance patterns of the parents' traits. By analyzing the alleles passed down from each parent, one can determine the possible combinations of genotypes and corresponding phenotypes that the offspring may inherit.
Punnett Squares do not directly tell you the percentages of phenotypes and genotypes, it tells you the probability of the expected genotypes. Based on the Punnett Square, you can infer about the genotypic and phenotypic ratios.

Different genotypes don't always change your phenotypes because of mutations

No.
By observing the phenotypes of individuals in a pedigree (such as their physical characteristics or traits), one can infer the genotypes that may be responsible for those traits. By looking at patterns of inheritance within the pedigree, such as autosomal dominant, autosomal recessive, or X-linked inheritance, one can make educated guesses about the genotypes of individuals based on their observed phenotypes. However, the presence of genetic variability, incomplete penetrance, or phenocopies can complicate the prediction of genotypes solely based on phenotypic information.
To effectively write genotype and phenotype ratios in a genetic study, one must first determine the possible genotypes and phenotypes based on the traits being studied. Then, the ratios can be expressed by listing the different genotypes and phenotypes and their frequencies in the population being studied. This helps to show the inheritance patterns and relationships between different traits.
