The alpha particles are too large to fit through the gaps between the particles of the paper.
Loosely speaking, yes. That is not to say alpha particles are totally harmless, but they are a much lower threat than, say gamma particles.
No. An alpha particle can
First of all its a Alpha particle, and a gamma wave, Paper can stop alpha, and nothing can stop gamma, but it is slowed down by lead, and concrete.
A lot of things, but I think you might be referring to which form of radiation since this is the classic answer as to what would stop Alpha radiation. Furthermore tinfoil would stop alpha and beta radiation and lead would stop alpha, beta and gamma radiation.
A few millimetres of lead.
Alpha.

A sheet of notebook paper will stop alpha particles. Depending on their energy, alpha particles, which are helium-4 nuclei (two protons and two neutrons), will only travel a few feet in air. Use the link below to learn more.
Alpha particles are the least penetrating of the primary particles because they have the most mass and the most charge. They can be stopped with only a few inches of air, or even by a sheet of paper.

Yes, Alpha radiation could be stopped by normal paper.
A few millimetres of lead.
No

They stop.
