No, the ancient Egyptians did not invent steam engines. The concept of a steam engine was developed much later, primarily during the 17th and 18th centuries, with notable contributions from inventors like Thomas Newcomen and James Watt. However, ancient Egyptians did utilize steam in various ways, such as in temple rituals, but they did not create a functioning steam engine as we understand it today.
yes
He built steam engines.
They did not. Egyptians invented paparus, not paper.
Yes.
Steam engines presently produce more power than all other types of engines combined. Most steam engines take the form of the steam turbine engine. The steam turbine is responsible for generating about 86% of the electric power used on this planet. Reciprocating steam engines are still in use for limited applications, but are generally considered obsolete. Steam engines, either the piston or turbine type were used on most big ships until recently, and there are still a few steam locomotives about.
yes
No, he improved on Newcomen's design for pumping engines.
He didn't. The basic concept of the steam engine was known to the ancient Greeks well over a millennium before Jacques Perrier was born. Perrier did work with steam engines and developed several improvements for them, but he certainly did not "invent" them.
There is no specific collective noun for steam engines, in which case any noun suitable for the context will work; for example a collection of steam engines, a display of steam engines, a museum of steam engines, etc.
No, but they did invent paper!
They are called steam trains because they are pulled by steam engines.
Watt developed the concept of Horsepower and the unit of power the Watt. He did not invent the steam engine but did make significant improvments to the Newcomen steam engine. Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines.
He did NOT invent the steam engine. He improved it in two ways. 1) He investigated why early steam engines were so inefficient, and how to cure that problem. 2) He developed rotative motion so that the previous engines, which were purely reciprocating steam-pumps for mines, could be made to drive factory machinery. He was the technical one of the business partnership with Matthew Boulton, a machinery manufacturer based in Birmingham (English Midlands).

No, the steam engines is the bestest. Get your grammar right.
He built steam engines.
