In the following sentence, which one of the above will be apt?

It's good to know that John along with Julie, Julia, and Zehrs ___ done a wonderful job that requires accolades and lots of appreciation.

Grammatically, with this structure, it should be 'has'; there should also be a comma after 'John' and after 'Zehrs':

'It's good to know that John, along with Julie, Julia, and Zehrs, has done a wonderful job that requires accolades and lots of appreciation. "

This sentence subordinates Julie, Julia and Zehrs to John; if you wish them to have equal recognition, then you could re-phrase and re-punctuate to 'It's good to know that John, Julie, Julia and Zehrs have done...'

thanks a lot for the answer...

it helped to come out of the confusion.
I wonder why grammars are more interested in their rules than put nearer grammar to the 'reality'. If we could 'see' the sentence, we realise that the wonderful job was, in fact, done by four people, so it could be obvious that the verb should be have, but grammars, are stubbornly more interested in the subordinated sentence. Then, what's more important? To try to respect a rule or reflect the reality as it is?
Not at all, Latin. 'Have' does not express the speaker's intention. The speaker here, for some reason, wishes to single out John for special mention, or had previously mentioned Julie, Julia, and Zehrs, and wishes to subordinate their names slightly. Such clauses are indeed reflecting the subtle reality of what the speaker wishes to express, and are a useful tool for the purpose.
