That depends on the specific radioisotope. For instance, uranium 238 emits an alpha particle during radioactive decay, reducing the number of protons and neutrons in the nucleus by 2 each and producing thorium 234. On the other hand, carbon 14 emits a beta particle (an electron) during radioactive decay, decreasing the number of neutrons and increasing the number of protons by 1 each and producing nitrogen 14. There are quite a few other examples with different changes depending on the type of radioactive decay.

No, most isotopes are not stable. Many isotopes are radioactive and decay over time, releasing radiation in the process. Only a few isotopes are stable and do not undergo radioactive decay.
To fully explain radioactive decay you need quantum mechanics.
There is a very wide range of half-life for different radioactive isotopes, ranging from the billions of years to very small fractions of a second. So some isotopes disintegrate immediately, and others last a very long time.
The radioactive decay of americium 241 is by alpha disintegration; the disintegration of radioactive krypton isotopes is by beta particles emission.
"Daughter isotopes" are called the decay products of an radioactive isotope.
No stable isotopes.
See the link below for radioactive decay chains.
By radioactive decay of Ds other radioactive isotopes are appearing.
