Yes, many of them are. In fact, both of the Voyager probes are still transmitting data, even from beyond Neptune and past the "heliopause", the boundary between the solar system and interstallar space.
Planets that have been visited by spacecrafts include Mars, Venus, Mercury, Jupiter, Saturn, Uranus, and Neptune. Additionally, the spacecraft Voyager 2 has conducted flybys of both Uranus and Neptune.
There are several planets in the solar system that have yet to be explored extensively, including Uranus and Neptune. However, all the planets have been visited by spacecraft, with flybys and some dedicated missions to study them. Currently, there are no plans for new missions to these planets, but their moons remain interesting targets for future exploration.
All four outer planets. Voyager 1 flew by Jupiter and Saturn only, and Voyager 2 flew by Jupiter, Saturn, Uranus, and Neptune. Pluto, which is no longer considered to be a planet, was not included in the fly-by.
Humans have visited the Moon, Mars, Venus, and multiple spacecraft have traveled to Jupiter, Saturn, Neptune, and Pluto. However, manned missions have only reached the Moon and Mars.
There have been no human space missions to Mars. The only missions to Mars to date have been through flybys with space craft, orbiters, and land rovers.
Flybys was created in 2003.
Voyager 1 was launched on September 5, 1977from Cape Canaveral, Florida. Voyager 2 was launched on August 20, 1977 from Cape Canaveral, Florida. They both performed flybys of Jupiter and Saturn, while Voyager 2 continued on to Uranus and Neptune.
The only spacecraft to pass by both Uranus and Neptune was Voyager 2. It was launched by NASA in 1977 and conducted flybys of several planets in our solar system before reaching Uranus in 1986 and Neptune in 1989. Voyager 2 provided valuable data and images of these two gas giants.

As of 2021, there have been over 20 spacecraft missions that have visited Venus, including flybys, orbiters, and landers. Some notable spacecraft include the Venera probes launched by the Soviet Union, the Magellan spacecraft by NASA, and the Akatsuki probe launched by JAXA.

Yes. In fact. the NASA "Messenger" probe was launched on August 3, 2004 and is on its way there now. In fact, it has done two close flybys of Mercury, and will settle into Mercury orbit in March, 2011.
No Honey No.
All four outer planets. Voyager 1 flew by Jupiter and Saturn only, and Voyager 2 flew by Jupiter, Saturn, Uranus, and Neptune. Pluto, which is no longer considered to be a planet, was not included in the fly-by.
There are two. Mariner 10, and Messenger. Mariner 10 was launched in 1973, and is believed to still pass Mercury every six months. Messenger was launched In 2004, and as of today is still involved in flybys collecting information. There are also two planned expeditions to Mercury, one by the European Space Program, the other by Japan's.
