In the project description it mentioned using a List of HashMaps, but I was wondering if I was allowed to import other libraries such as Stack. I can treat the List like the stack and I am currently debating which route to take, but I wanted to make sure it was even acceptable to import special libraries or use only the ones mentioned in the project outline.
You may use Java Stacks, but you will find they don't give you quite what you need.
Is value in TestSym supposed to be an int? It is in the startup tar but it's a string in the proj1.pdf. Also, do we only have to modify SymbolTable and P1?
The startup tar is just to show you the general idea. You might have to completely rewrite it, including all its Java files.

How should string literals that cross line boundaries be handled? For example, "hello world". What should I save into the string literal token object?
That's up to you. You can call the entire set of characters erroneous. Or just the first quote. Or you can try to recover by treating up to the end of the line a string.
Is the empty string "" a valid token?
Yes.
