New Horizons
For right now no. But the U.S has sent out a probe to get pictures from pluto
yes
The probe that is headed to Pluto is called New Horizons. It was launched by NASA in 2006 to study Pluto and its moons.
On January 19, 2006 a space probe was launched and sent to Pluto. It was expected to reach Pluto in 2015. So it would take about 9 years to get to Pluto.
Pluto was to far out of the way and of little importance when earlier probes where sent to the gas giants. but as i type this there is a probe on it's way to Pluto rigth now.
No current missions are being sent specifically to Pluto, but the New Horizons spacecraft conducted a flyby of Pluto in 2015 and provided valuable data about the dwarf planet. There are no upcoming missions planned for Pluto at this time.
No probes have been to Pluto yet, but the New Horizons probe is currently on the way there.
No, as of 2017, nothing sent from Earth has ever landed on Pluto. The New Horizons spacecraft did a flyby observation (2015-2016) but did not land.

Actually, no probes have ever been sent to Pluto. Even Voyager 1 and 2, which flew beyond the orbit of pluto in 1989, didn't do a fly-by of the planet (it was elsewhere in it's orbit at that time, and there were no plans to visit Pluto anyways).
That droid is a probe droid, but to be more specific, a Viper probe droid.
No. Makemake was discovered too recently for us to have sent anything there. It takes years to plan such a mission and would take years for a probe to visit something as far away as Makemake. The most distant object we have visited so far is Pluto.
