Can you activate Counter Gem if it's the only card in your Spell/Trap Zone?!
Counter Gem is activated with no other Spell/Trap cards you control.
No. You must already control another Spell/Trap; Counter Gem can't be activated as the only card in your S/T Zone.
If Call of the Haunted revives Ruby Carbuncle and I chain Counter Gem, when is Carbuncle destroyed?!
Call of the Haunted revives Ruby Carbuncle and Counter Gem is chained, sending Call to the Graveyard.
Call of the Haunted's destruction is not an effect and happens immediately when Call leaves the field, so Carbuncle is destroyed during Counter Gem's resolution.
