Thanks everyone

Hello,

Question 1:
For example, 2 people, for example (Sarah and John) answer my question in here, and I want to thank both of them. Which of the following can be used?

1. Thanks everyone.
2. Thanks everybody.
3. Thanks Sarah and John.
Any better suggestion?

Question 2:
Does the third one mean than I thank Sarah more than John because her name comes first? If yes, what changes we can apply to thank them equally?

Thanks.
