A plugin is basically an addon, application that can be loaded into a host such as Sonar and perform various functions - which can be almost anything: FX (delays, echos, whatever) of SoftSynths, and so on.
Sonar comes wth a bunch of plugins already. There are DXi and VSTi plugins (different formats) that Sonar can host.
Dynamic range is basically the range of level over the entire audio spectrum. FOr example, in a typical classical music piece, there will be a wide/large dynamic range - meaning there will be many low level (softer) moments and many high level (louder) moments. In a lot of 'commercial' music, there has been a tendency to keep the dynamic range limited - meaning it sounds as if every moment is as loud as it can be. In other words a small dynamic range. A wide dymanic range will have low and high peaks. This is not a technical explanation, but I hope you get the concept.
Mixing is basically when you put all the separate elements in a project together to form a stereo (or other type) of 'final' composite - including any FX or other processing (EQ, compression, and so forth). For example, if you want to create an MP3 of your project, you would mix down to a stereo track and then export that to an MP3 format using either the Sonar mp3 encoder or some 3rd party one.
As for levels, of course one should be careful not to go above 0dB to avoid clipping (though some people DO!), but getting good level isn't just a matter of getting tracks and mixes close to / near to "0" ... some digital sounds don't need to be that 'hot'. Analog sounds should be recorded at 'good' levels (and that is subjective, frankly).
My approach is to record tracks at levels which do not introduce noise (usually because they are too low), but not such hot levels that the recording gets "saturated". Though sometimes that "saturated" quality is a sound of its own (grin). It's tricky stuff and takes some experience, skill, and good ears. But there are some basic guidelines most people follow. Use your ears, though - that's usually the best approach.
HOpe that helps a bit ... this is just my understanding of it all based on my own experience. There are others around here that can offer much better and more technical explanations, though, I'm sure.

I have not got into plugin yet. Is plugin a general term?
Is anything that can be applied to a wave form is called a plugin?
are Chorus/Reverb/Delay plugins? Thanks.
Can anyone explain to me what is dynamic range? is it a distance from the lowest point to the highest point of a wave form?
I could not see a track that is a mix of all other tracks in SONAR. Does mixing simply add all tracks together applying nondestructive FX? If this is the case, the mix must come to distortion(above 0db) ?
Thanks
