Given the context, I'm unsure as to what you expected. Given that you
have posed no question - I'm unsure as to the point of your post. Was
there a point?

A list of variations from rkhunter's default expectations is of
immeasurable concern.
Is this a debian based system? - if so did you create a debsum database
on creation? Have you run one since?
Did you create a read-only SHA256+ hashed db on your system before
exposing it to the intertubes? On a removable device? If the answer to
those questions is no, I'm uncertain of what you could expect without a

I ask partially because others may jump to the conclusion that belatedly
installing and then running rkhunter may prove of use as a substitute
for prior planning and proper deployment.

Perhaps I'm putting too much into the assumption you simply installed it
onto a box that has been running unmonitored for some time, ran it once
without reading the man file and are now concerned by results you don't
understand. But I'm guessing.

Given more time and sleep I hope I would phrase the previous
differently, but as that's not the case I hope instead that it may
provide some help with the question you failed to ask. :/
