Can a hybrid be a mutation? If we check the DNA of any organism, excepting clones, aren't all individual organisms unique? Do mutations occur all the time in sexual reproduction? Basically is variation a "slight" mutation?

In sexual reproduction there is intermixing of genes of the same species.


Part of your question is true. Individuals of the same species have identical genome. But during sexual reproduction there is shuffling of genes.
Due to shuffling of genes there is variation
I may suggest a simple example. In card game the number of cards is 52. But due to shuffling 'n' number of re combinations exist. The number of cards remain the same.
The number of cards is the genome. The possibilities is the variation. Variation is not the mutation. It is just expression of combination of same genome.
