32 is correct. You would normally receive 8, but that will double with the 1st parallel lives to 16, which will double again to 32 with the 2nd parallel lives.
W may only be paid with white mana. U may only be paid with blue mana. B may only be paid with black mana. R may only be paid with red mana. G may only be paid with green mana. C may only be paid with colorless mana. 1 may be paid with white, blue, black, red, green, or clolorless mana.
You don't trigger Garruk, Primal Hunter's abilities. All his abilities are activated, not triggered.
In the scenario you described, you would indeed get 32 tokens. Parallel Lives has a static ability with a replacement effect. When Garruk, Primal Hunter's -6 ability resolves, both of those replacement effects will try to double the number of tokens you get. You can only select one. Then, once the number of tokens have been doubled, the unused replacement effect sees that it still applies, so you use that one too. In the end, you have doubled the number of tokens twice, so the ability gives 32 tokens when it resolves.
if i have 8 lands in play and 2 parallel lives when i trigger garruk, primal hunter's big ability, how many 6/6 wurm tokens do i receive? 32?

If it was additive, you'd recieve 24 wurms (8+8+8)..
If it was exponential you'd recieve 216 wurms (8^6^6)
