Uranium is paramagnetic at room temperature. When it is kept in low temperatures (below it's Curie point) it exhibits magnetic properties, and is attracted by a magnet.

Paramagnetic means that it's attracted by a magnet. The other two materials are diamagnetic, meaning they are repelled by magnets. Here's my source: https://periodictable.com/Properties/A/MagneticType.html

No. Copper is paramagnetic, and it is not influenced by a magnet. Only ferri, ferromagnetic substances are influenced.

My link says it's diamagnetic though (and I do too). Ferromagnetic substances can hold a magnetic charge (i.e. become permanent magnets)

you should also know that bismuth and lead are diamagnetic materials that repelled by magnetic field, copper is not ferromagnetic, ferromagnetic materials include nickel, iron , cobalt and many other alloys containing this metals
