They are all different characters? Posting a question with what is XYZ is not helpful, what have you read in the manual on these, where are you using them etc?

At a guess:

1) : - used for stating lists of variables with incremented numeric suffix, like var1, var2 etc.

2) & - And, logic gate

3)~ - could mean anything, I use this as split in report for instance.

4)@ - hold pointer when reading file

5)@@ - hold pointer until next iteration

If the above, then they are all well described in the manual.

@RW9:

Actually, it is also an alternative form of the NOT operator, e.g.

408  %put %eval(1~=2);
