I disassembled a dead laptop battery and found 6 AA size batteries interconnected. 5 of them still give 1.2V on meter.
If I replace the defective one would the pack be usable again and would it keep charge?

I am answering here because others might look up the subject.
Mixing old and new batteries is false economy. You are likely to find one of the remaining 5 batteries to fail soon.
The phrase "throwing good money after bad" is very much applicable here.
They're not AAs, they're 18650 Lithium-Ion batteries, nominal voltage 3.6V.
At 1.2V your batteries have been over-discharged, they're finished. If you recharge them they won't last.
You can replace all cells with quality 18650 LiIons which aren't that expensive ($6-8 a piece). Purchase from a reputable source (ie, not cheap knockoffs from ebay).
