I don't think they would be dwarf planets, but something else.

The International Astronomical Union (IAU) defined in August 2006 that, in the Solar System, a planet is a celestial body that:

1 is in orbit around the Sun,
2 has sufficient mass to assume hydrostatic equilibrium (a nearly round shape), and
3 has "cleared the neighbourhood" around its orbit.

A dwarf planet must meet 1 & 2. Are Jupiter's smaller moons round?

Jupiter has rings, so any planet would have to have cleared the rings around their orbit. I think that applies to the Galilean moons. Juno orbits outside the solar plane, so I'm not sure if that is a rule for a planet or not.
