In the real world, the session layer doesn't actually exist. The OSes have grouped the session, presentation, and application layers all together in the application layer. It is up to an application to do sessions. Rather than create a session with a server, the application creates a session with a proxy that then stands in for the application.

A gateway is a device that can send traffic to a different network. The gateway operates on the same data-link LAN as the source device, which sends traffic destined to a different LAN to the gateway.
The OSI model doesn't have a "dialogue layer." I presume the quote means the application layer.
Typically, a proxy server is for an application (usually web browsing, but not limited to that). You would have your web browser (or other application) configured to use the proxy server instead of the default gateway for the host, and the application traffic is then sent to the proxy server that stands in (proxies) for the host when communicating to a web server. The proxy server can then be configured to perform security functions such as denying unsafe web sites, data inspection for malware, etc.
I'm not sure of the source of you quote, but it seems to use its own, non-standard terminology, so I would look for a different learning source.

@YLearn, I kind of wondered the same thing, but it does have "link-level" in it. In any case, it seems a poor source (at least in English). I have recently seen a lot of things that simply make up different terminology, presumably to make it easier to understand, but it seems to confuse the situation even more.

@YLearn, I was certain that the recent trend to use the term "packages" instead of "packets" on the SE technology sites was due to translations, but I was browsing in a bookstore a couple of weeks ago, and I ran across a book in English that used that term. I suppose it is possible the book started out in a different language and was mistranslated, but the people who buy it will not know that.
