they are called planetesimals
Accretion
dust and gas
Only if they fall into elliptical orbits that take them close to the sun. So long as they stay in the Ort cloud, they're planetesimals.
Large planetesimals have gravitational pull and attract smaaller ones.
As earth formed, most planetesimals were attracted by the earth's gravity and coalesced with earth.
By "accretion" of "planetesimals" from the "protoplanetary disk".
planetesimals formed the disk

There is nothing on the list you provided that resembles them in any way.
The fission theory, the capture theory, the condensation theory, the colliding planetesimals theory and the ejected ring theory.
No. Stars are many times larger than planetesimals.
The fission theory, the capture theory, the condensation theory, the colliding planetesimals theory and the ejected ring theory.
Planetesimals made from ice and sometimes rock are called comets.
The asteroid belt formed from the primordial solar nebula as a group of planetesimals. Planetesimals are the smaller precursors of protoplanets. Between Mars and Jupiter, however, gravitational perturbations from Jupiter imbued the protoplanets with too much orbital energy for them to accrete into a planet.
There are six different stages in the condensation theory. These include the formation of a nebula cloud, the formation of a sun, the formation of planetesimals, the expulsion of gases from the forming sun, the growth of the planetesimals, and the formation of larger planets from planetesimals.
