Can I join PVC pipe with ordinary glue instead of PVC cement?

Not for a joint that has to hold water or pressure. PVC cement softens both faces so they finish as one piece. A general-purpose adhesive sits on the surface and is a repair at best, not a plumbing joint.

Do I have to use primer with PVC cement?

Follow the pipe standard and the cement can. Primer cleans the gloss off and starts softening the plastic; where the code or the product calls for it, skipping it is how a joint looks assembled and still leaks.

Can solvent cement repair a cracked PVC pipe?

No. Cement welds faces that already touch. A crack, a chip, or a fitting that will not close needs a replacement section, or a filled repair that is not treated as a pressure joint.

Will PVC cement work on ABS or CPVC?

Only a cement whose label names that plastic. PVC, CPVC, and ABS each have their own formula; the wrong can either does nothing or attacks the fitting.
