No. The last new planet discovered in our Solar System was Neptune, in the year 1846. There are almost certainly no planets in the Solar System waiting to be discovered.
Pluto, and a few other objects now classified as "dwarf planets", have been discovered since, but they're tiny ... Pluto, for example, is significantly smaller than many of the actual planets' moons (the Earth's Moon, four of Jupiter's moons, three of Saturn's moons, four of Uranus' moons, and one of Neptune's moons are larger than Pluto). The only planet having moons at all that doesn't have at least one moon larger than Pluto is Mars.
Not in our own solar system. The orbits of all the planets in the solar system have stabilized, and there isn't enough mass in the remaining asteroids to form a new planet. Else where, however, there are solar systems that are still forming, with new planets that are yet to form.

Yes, there are over 200 more planets outside the solar system, these planets are called extrasolar planets. There are also more then 170 solar systems inside of the Milky Way, on average astronomers find around 25 new planets a year.
Well, we cannot say that they are two new planets but they are new discoveries and considered as dwarf planets. Xena and Ceres
New planets are more or less constantly being discovered outside the Solar system. There are almost certainly no unknown planets still lurking within the Solar system, though.
