It's possible to arrange for transparent shapes to appear in the animation
sequence and trigger mouse over hyperlinks

BUT

You will probably need to arrange for the pointer to be always visible to do
this. You can use kiosk mode, press ctrl A at the the start of the show or if
it's on your own PC we have a free add in to acheive this in normal show mode.

I hope that John answered your question because I'm still not sure what
you want to have happen on Slide 5. Is this an automatic link; i.e.,
whenever the user is done with slide 5, it will go to slide 7, or are
they supposed to click on something specific. If so, when are they
supposed to click on something specific? If it is automatic, then I
would suggest some kind of custom show. For example, put slide 5 and 7
in a custom show. The link on slide 4 link will link to the custom show,
and it will automatically jump from slide 5 to slide 7. Alternatively,
you might hide slide 6. The link from slide 4 to 6 will still work, and
after slide 5 is done, it will skip slide 6.

If the jump from 5 to 7 is supposed to be triggered by a click of
something, then that something, whether it is animated or not, should
have the hyperlink assigned to it. Alternatively, John's solution might
be what you want.
