Well, yes, that's how stars start - and you could call it a "baby star". However, please note that:* This is usually called a "protostar".
* The protostar will be made up of whatever material is floating around; it may be hydrogen and helium, but for newer stars, it may also contain some amount of metals (i.e., heavier elements, such as oxygen, carbon, etc.). And in the future, the "metal" content of new stars will increase.
No, it is not. A cloud of hydrogen and dust need not form a star: they could form a failed star.
That would be a nebula, which is an interstellar cloud of hydrogen gas, dust, and plasma. It is the first stage of a star's cycle.

A nebula is a cloud of gas (hydrogen) and dust in space. Nebulae are the birthplaces of stars.

A gas cloud. It must contain dust to form planets. (And lots of hydrogen to form a star.)
