To date, only one has reached Neptune so far.
Voyager 2 did a flyby of Neptune in August 1989, sending images and data back to Earth.
Space probes have been sent to Neptune to study the planet's atmosphere, rings, and moons, and to gather data that can help us better understand the outer solar system and its formation. The information collected from these missions can also provide insights into the composition and behavior of other gas giants in our galaxy.
Unmanned space probes have been sent to various destinations in our solar system, including Mars, Venus, Mercury, Jupiter, Saturn, Uranus, Neptune, and Pluto. They have also traveled beyond our solar system to study interstellar space.
The Voyager 2 went to Neptune on it's last stop in the solar system.
there has been 16 probes that had been sent to venus.
Yes, there have been probes sent to Mercury. Messenger and Mariner 10.
At current we have sent, or are sending, probes to all of the planets in our solar system. The probe Voyager has visited several planets, including Jupiter and Neptune, while Cassini is currently in orbit around Saturn.
Only one spacecraft has visited Neptune: NASA's Voyager 2 probe, which made a flyby of the planet in August 1989. Voyager 2 provided our first close-up images and scientific data of Neptune and its moons.

If landing probes are mentioned, no not yet.

Not exactly. The Voyager 2 space probe did a flyby of Neptune, but since it never actually orbited the planet, it can't be considered a satellite. Neptune does not have a solid surface, so nothing could ever land on it.
Some of the probes that have been sent to Venus include the Soviet Venera missions, NASA's Magellan spacecraft, and the European Space Agency's Venus Express. Currently, the planned VERITAS and EnVision missions by NASA and the European Space Agency, respectively, aim to further explore Venus in the coming years.
