Is there any option to change this plugins list in Alphabetical Order?
If you mean alphabetical order of the directories (might be case sensitive depending on the OS): it is already sorted that way.
If you mean alphabetical order of the names of the plugins: no, there isn't any sorting option implemented.
How To List Plugins In Alphabetical Order?
Assuming you mean order of the names of the plugins, based on the previous comments, you should rename each plugin directory accordingly. You should ask the developer of the plugin if this is possible as, sometimes, URLs are hardcoded to reach a file under the plugin directory.
EDIT:
I ended up creating a pull request with some changes, including sorting plugins by name. The pull request is https://github.com/q2a/question2answer/pull/155 and the particular commit that you might be interested in is https://github.com/pupi1985/question2answer/commit/130128571afd752d6439f2a82b34e56208cc74a8 . Please, take a look at it, test it and report back :)
