What is a proplyd?
it is exactly protoplanetary disk.
How the rocky inner planets were formed?
By "accretion" of "planetesimals" from the "protoplanetary disk".

What is it called when planets are formed?
Accretion because usually they form from a protoplanetary accretion disk.
What is the early phaseof a star called once the gas and dust begin to coalesce into a shpere?
A protoplanetary disk.
How did Uranus form?
As best we know, the same way all the other planets did: accretion of objects in a protoplanetary disk.
Are planets formed from the same clouds of gas and dust as stars?
Yes. As a new star is forming it is surrounded by a disk of gas and dust called a protoplanetary disk. Planets, asteroids, and comets all form from this disk.
Where did planets made of mostly gas and ice form protoplanetary disk?
Far enough from the new Sun that they did not "evaporate". In other words, towards the outer rim of the main part of the disk.
How did Jupiter become the biggest planet?
Jupiter is the biggest simply because it got the most stuff out of the "protoplanetary" disk from which the planets formed.
What causes the moon?
The moon is a natural satellite that revolves around the earth. It is believed that the moon formed out of a collapsing region of the protoplanetary disk.
How are natural satellites formed?
Natural satellites are believed to be formed from the same collapsed part of the protoplanetary disk that created its related, primary planet.
What will the protoplanetary disks eventually become?
That depends what the disk is forming round. If it is a large black hole it will form a quasar, if it is round a star, it will form planets (a solar system).
