Neutron emission is typically related to fission, but they can also be released by themselves in certain cases where there is a excess of neutrons, such as beryllium-13 and lithium-10.
Radioactive decay; beta decay is a type of radioactive decay in which a beta particle (an electron or a positron) is emitted
only the gamma decay.
Uranium-235 will not beta decay first. If you google "Chart of Nuclides" you can follow the entire decay chain yourself using each isotope's most likely decay type.
Naturally occuring Radon gas decays by alpha particle emission. However, many of the decay chain products have very short half lives, of which some decay by alpha particle emission and others by beta particle emission.
X-rays are not a type of nuclear radiation. They are a type of electromagnetic radiation.

Helium has two naturally occurring isotopes, 3He and 4He. Both are stable, so helium does not undergo decay in nature. Several synthetic isotopes exist. 5He is highly unstable and decays to 4He by emitting a neutron. 6He undergoes negative beta decay, producing 6Li. It has the longest half-life of any radioactive helium isotope, at 0.808 seconds. 7He is highly unstable and decays to 6He by emitting a neutron. 8He undergoes negative beta decay, followed immediately by emitting of a neutron, producing 7Li. Its half-life is 0.122 seconds. 9He is highly unstable and decays to 8He by emitting a neutron. 10He is highly unstable and decays to 9He by emitting a neutron.
If an electron is released from the nucleus (and not from an electron shell) then it would have been emitted by a neutron in beta decay. In beta-minus decay, a neutral neutron emits an electron and an anti-neutrino and becomes a proton; in beta-plus decay, a proton emits a positron and a neutrino and becomes a neutron.

This type of decay is called β- (beta minus) decay. A link is provided to a related question with a descriptive answer that details the process.

Yes, gamma rays are ionizing but not as strongly ionizing as other forms of radiation such as Alpha, which is the strongest due to it's size, therefore making it more likely to collide with atoms and remove electrons. Gamma is only weakly ionizing because it is a small photon.
