Please find the attachment of the Blast results of a sequence. I am unable to interpret the best identity among the results as the results give same Query %, E value and % identity with different species.
First look at sequence identity, e-value and query coverage. Then you can perform phylogeny, the sequence very close to your sequence will be the best hit.
Based on the result, all of the sequences seem homologous. It means all of the sequences are present in all of the hits (match). I think you need to take a longer sequence to figure out the best match.
