I noticed that there are one website that shows the views of other planets and stars from earth(it says 'as seen from earth' but never said weather using naked eyes or telescopes)which looks very clear and nice.

No. You can easily see several of the planets if you know where to look. They can be quite bright.

Mars appears like a bright red star. Venus appears like an even brighter yellow star. Mercury and Jupiter are barely visible to the naked eye. Saturn is barely perceptible.
These, for nearly all of mankind, were the only known planets identified because they "travel through the night sky faster or differently than the stars". When Galileo Galilee perfected the telescope, not only was Uranus discovered, but also were the moons of those known planets.
The other planets were discovered (or predicted first) because there was need to account for greater mass influenences upon our solar system. This means that the known planets were orbiting our sun in ways that were different than what normal paths should be.
Suppose you had a tennis ball on a long string, and swung it around in a big circle. Each time around, the ball barely tapped a few tree leaves nearby, but you can not see the tree. You would notice the change in the ball's normal path, and might be able to guess that something is slowing the ball and changing the path.
If you see that change over and over, and see a pattern, you might find tools to help you "see the tree". That is how Neptune, "Pluto", Charon and Xena were found. The known planets and comets had paths that changed by "something out there". We now know, after careful measurement, that it was other planets changing these orbits.

The planets were observed to have different motion than the stars long before telescopes were ever invented-- that's why they were named after gods/goddesses, because they didn't appear to follow the same laws as the stars, i.e., they were "special". Venus and Mars are particularly easy to see from the earth with the naked eye.
Of course, you can see a lot more with a telescope. ;)

We can see many of the other planets with the naked eye. We can see Mercury, Venus, Mars, our Moon, Jupiter, and Saturn. But they will be very small and look at though they are stars.

Venus and Mars are the most easily viewable by the naked eye. In fact, one can even see their colors. Mars appears red and Venus appears yellow. One way to tell that you're looking at a planet is that it doesn't "twinkle," unlike stars.

No. Depending on your eyesight, most everyone can see Mercury, Venus, Mars, Jupiter, and Saturn. Some people with very good eyesight can see Uranus. I've never heard of anyone who can see Neptune with the naked eye.
