It depends on the CD's format, how it was burned, and whether the session is still open or not. If it is a CD-RW(Read/Write) you can erase these and re-write data on them. If you are trying to erase a store bought CD or a CD-R or CD+R you are out of luck, once these are burned they are done.
If the CD is a CD-R it is only "Writable," and cannot have songs added to it after its initial burn. If the CD is a CD-RW you should be able to "Rewrite" songs onto the CD and reburn them.

Yes. CD-RW drives are capable of writing to CD-R discs as well.
CD-R isn't rewritable at all. A CD-RW can be rewritten on.

If the CD Player will not read the CD then either there is something wrong with the CD or the CD player or the CD or CD player needs to be cleaned.
the CD drive has lasers which read the CD, so the CD has pieces that can be read.
