I'm using mysql as xampp(linux) component for my development works for a long time. But I wonder if I can use Oracle as my database. If I can which version should I choose that will fulfill my needs of production level development.
Also I've heard Oracle EE requires money for licensing. What facility they provide by licensing Oracle DB? Can it be used for development?(I'm just curious)
Oracle provides Oracle XE (Express edition) free for developer use which allows you to create and use databases of up to 4GB, use up to 1GB of RAM and use only one CPU. Anything more you gotta pay for it

I find myself in a position to work on Oracle Express for a project. Just curious will it continue to work with given provider in enterprise edition?
Is there any difference in Oracle provider for Entity Framework between Oracle Express & Enterprise Edition 12c?
Yes, it will work. ODP.Net (managed and unmanaged) can connect to all versions of Oracle and also to any platform. A good starting point to read is the Oracle Data Provider for .NET FAQ
And no, there is no difference.

Our production Oracle Database version is 10g.
I am trying to install either 11g or 12c on my local machine primarily to access sqlldr.
I am wondering if there are any compatible issues.
Metalink has the definitive client/ server compatibility matrix. It will depend on the full version of the target database. Assuming "10g" means 10.2.0.2 or later, you should be fine with a 12.1 client. If the database is running something earlier than that, you'd generally need an earlier version of the client to be safe.

To the best of my knowledge, Oracle Apex looks similar to Oracle SQL Developer. For all of my database development life, I have only used SQL Developer.
Are there any specific feature sets available in Apex that are available in developing Oracle databases that are not in SQL Developer, and visa versa?
Welcome to SO.
SQL Developper is a GUI tool to run ad hoc queries, develop stored procedures and similar, more like a GUI version of, command line tool, sqlplus.
On the other hand Apex is more for prototyping/developping some custom applications that some end user (or admin) would access using the browser (HTML interface).

I have a 4 Core 12GB RAM dedicated windows machine.I have Oracle 11g installed on it.
Could any body please help on the DB server parameters that can be tuned from a performance perspective.
Any reference to a credible url also is fine & will be of great help. Thanks..
Oracle provides a lot of online documentation including a lot of guides. The 2 Day DBA Guide for 11.2 has a section on Monitoring and Tuning the Database that can get you started. Other sections in the guide can be helpful as well.

A have some step by step description where downloading of OracleXEUniv.exe is one step.
But I cannot find what is it for? What is functionality of this file?
Than you.
OracleXE is the free version of Oracle's main database product. The "Universal" simply means it will install using the Universal character set instead of the Western European character set.
Oracle Database Express Edition (Oracle Database XE) is an
entry-level, small-footprint database based on the Oracle Database.
It's free to develop, deploy, and distribute; fast to download; and
simple to administer.
