I forgot what the name to the aquaman is but he gives all justice league members +1 a and d. If I have 3 do my other justice league members get +3 a and d? same with the green lantern that gives all attackers +2 a and d.

please quote the text of the card when asking questions.

Aquaman - King of Atlantis
While Aquaman is active, other Justice League characters get +1A and +1D.

(you can find them all at CoolStuffInc's website)

My understanding - if you have any number of Aquaman dice in the field, then the "while active" condition is met, and the other JL figures are +1A and +1D, regardless of whether you have 1 or 40 of them in the field.
