At this moment, you cannot - but I hope to introduce that functionality
in the next version.
I also want to know if I could know the nucleotide

Do you mean the proportion of each base at each site ? Once again I
have to say no, for the moment. Jalview calculates the percentages
internally when it creates the consensus histogram, but it doesn't show
the full profile to the user. Again, I think this will be introduced in
the next release.

Once again, no. Jalview's nucleotide analysis functions are very
primitive - if you can find another way to perform the test, then you
could create an annotation file to load back onto your sequences (or
alignments) so Jalview could view them. Have a look in the help
documentation to see details of the file formats.
I hope this helps
