Obviously, a body of water the size of a stream or river will succumb to the immutable forces of gravitational attraction, inertia, and the other laws of physics, and be forced to flow downhill. There are some rivers that run from south to north (which is opposite of most), and some that seem to run "backwards", but no rivers run uphill. The starting point of all rivers and streams is of a higher elevation than their end point.
Yes! On planet X.
There COULD be. It would have to be like this though.
A river would run down a hill. The water would gain enough momentum when it reached the bottom that it would run up the next hill. But no, there is no river that starts at the base of a hill and runs up. Gravity wouldn't allow that :)
Edit: Consider what happens at the base of a waterfall: water is pushed down and due to pressure is forced up with the flow. So yes, at some points in most rivers, water flows upwards, if slightly.
no. gravity pushes the water to fall downards
No. The flow of a river is the result of gravity due to the downward slope of the river bed.
Because rivers need to flow down. It wouldn't make sense if a river flowed up a hill.
yes

Water can flow up hill if there is some sort of machine that is able to pull it. Water does not naturally flow up hill it always flows downstream due to gravity.
Rivers flow down.
Small streams flow into rivers and the rivers flow to bigger rivers.
Rivers are not pure freshwater sources of water. As they flow to the ocean, they pick up small amounts of mineral salts. These slightly-salty rivers flow into the ocean, and as this is a continuous flow and there are thousands of rivers, all the salt builds up, causing the oceans to be saturated with salt. Also, because water evaporates and salt does not, the oceans get saltier over time.
If you can find a single one that flows uphill I will send you a picture of some money !
The Rio Grande and other rivers dry up before reaching the sea because humans take so much water from them. Some rivers may also dry up naturally, or drain into a salt lake with no ocean connection.

oklahoma's rivers flow south-east
all rivers end up in the ocean/sea
