The two tubular ones look like Hot Rock Lamps by Lite F/X. The cone shape one is a Wizard by Lava Lite
Do you know how old they would be?
Yep, 90s Lava brand Wizard and the "Hot Rock Lite." They couldn't sell a LAVA lamp since "Lava" was trademarked, so they cheekily skirted it by referred to "hot rock" and "liquid earth." The lava versions had boring flow, but the glitter Hot Rocks were nice and sparkly.
