So, how can I do this?
For example, my person goes right and camera starting to move to persons coordinates with acceleration, when he stoppes - camera moves to persons coordinates with deceleration. Of cource, I can make it by myself, but is there any library that can help me with it?
I'd suggest using Universal Tween Engine. You could add a short deleay and proper math equations to smooth out the camera transitions.

How can one create a scene/terrain like clash royal's game scene in blender? The game scene seems like top view but is not exactly top view. At what angle should the camera be placed to get that effect?
You would be looking for isometric projection or maybe 2.5D, also called 3/4 perspective. You can find several isometric tutorials on youtube.
While I'm not sure if there are any strict rules to follow unless you are making graphics that must fit in an existing game, it is common to use an orthographic camera at about a 45 degree angle.
Clash Royale looks like it could be close to a 45 degree orthographic camera angle.
I may be making this harder than what it really is, but I am also pretty new to developing games. Currently I am making a practice scene to get back used to the unity engine as I have not had time to use it since last summer. My issue is that I can not figure out how to lift the camera in game mode. Notice my photo below, and how much of the "underground" is showing. I want to raise the camera to keep it at the very least a specific y axis value, so that I can make less of the ground visible, and more of the background visible. If I am over complicating this, please also let me know. Thank you
If main camera is still then just lift the camera in scene view you can see changes in game view.
Or if camera moves with respect to player then you have to use a script and attach it to camera and get a reference of player transform in the script and according to the player position change position of the camera. Add an offset value in y component of the camera.
I have a Player in first person walking around on Unity terrain and I'd like to restrict the camera controls to the y axis (left/right) and automate the camera rotation of the x axis.
So looking up/down should require no player input, depending on wether you walk up a slope or down.
I'm not quite sure what to look for. You could probably do it with a Raycast, but I suppose there's an easier way?
There are a few built in camera scripts. you need to import that standard assets that unity has. And there are a few different ones that you could modify, but they do follow the player very well.
i am trying to build a game in which the player moves along the terrain which has ups and downs. I also want the background to move in the opposite direction of the player movement. How to achieve this ?? Here the player is moving in Xaxis and Yaxis like Ski Safari game and camera is moving with the player. Please help.. Thank you in advance.
There are several ways you can do this, I would suggest this: http://answers.unity3d.com/questions/19848/making-textures-scroll-animate-textures.html
You could also use Fractal Textures, Unity3D provides an example of this in their procedural generation example on their website: http://u3d.as/content/unity-technologies/procedural-examples/3zu
How should I go about adding camera collision to a terrain in three.js.
The terrain is from 'mrdoob's three.js' examples and is randomly generated and I am currently converting it to height map.
I am thinking of implementing the collision as follows:
Create a 'box' object around the camera
If the box object is not touching the terrain, move the camera down.
If the box object IS touching the terrain, keep the Y axis of the camera.
How should I go about doing this?
The theory is that you send a ray from the location you are (camera position) straight down. You find the intersection point and based on the distance you decide what to do. Implementation wise I cannot help you but THREE.Ray should help you.
