Jupiter and Saturn are easily visible; indeed, Jupiter is more prominent
than Mars, being brighter and whiter. Mercury is technically visible,
but it never gets very far from the Sun, so it's hard to catch sight of.
Uranus is visible, but with an orbital period of 84 years, pre-telescopic
peoples never identified it as a planet. Neptune and Pluto are completely
beyond naked-eye astronomy.
