I want to understand how huge graphs can be implemented, so that graph algorithms run faster with huge graphs.
Maybe you should look at a famous graph library, e.g. boost graph library
The core idea for graph representation is incidence matrix. The rest depends on what you need. For example possible solution oriented on quickly finding neighbours are adjacency matrices.

I recently got interested in lockless programming and attempted to write implement a fixed-size mostly-lockless vector (github link). While it works, I'd love to get some feedback from more experienced people if my logic looks buggy or suspicious.
Are there any standard techniques that are particularly useful when testing out lockless data structures?
std::vector is lockless. In general, any good vector implementation will be lockless, because the granularity of a vector is too low for locks to be of any use.

I want to design a physical particle system in order to model/simulate a flowing water on a terrain. I want to use C (maybe C++) in order to do that. Do you guys know any good examples or a good starting point to do this?Thank you!
maybe can be useful Fluid simulation library

I would like to know if there is an already samples of doing data flow graphs using QT graphics API.
I would like to see some samples to get started with.
Qt comes with various examples that might help you get started.
The following two examples come to mind:
The Diagram Scene Example
Elastic Nodes Example
Have a look at those for some inspiration.
Qt-based, but a separate project which is possibly more along the lines of what you're looking for is NUKEEngine's Qt Node Editor.

I'm trying to pick out my next hackery project. It'll likely be one of the following:
A sparse radix trie Implementation with extremely fast set operations
A really good soft heap implementation
A bloomier filter implementation
A collection of small financial algorithms, such as deriving total returns given a set of dividends and minimal information about them.
But I can't choose. So I thought I'd put my fate in the hands of my peers. Which of those four would you find most useful? Most interesting to work on? Which do you think is the most needed?
I didn't know what a bloomier (maybe Bloom?) filter is until reading your question. Sounds cool and useful.

can i get the link to Quick look up of data structures..
Search Google for "data structures C++"
Wikipedia - List of Data Structures
...doesn't get much quicker than that.
If your looking for windows related data structures, use the built-in offline msdn library that ships with most Visual Studio versions(which can be extended by certain SDK's, like Direct X)
