How can I downgrade my MySQL database from version 6 to 5? Since I manage to install some packages only support to ver 5.

Your best bet is going to be trying a dump & restore. As long as you didn't use any MySQL 6.x functionality, it should go smoothly.
As always, backup before doing potentially dangerous actions.

I am using Mysql, now i would like to upgrade to MariaDB.
The MariaDB guy say: "MariaDB is a binary drop in replacement for MySQL"
Anybody who have used and using MariaDB, please suggest me: should or don't should to switch to MariaDB from Mysql and the reasons why!
I would like the suggests come from experience.
Thank for any suggestions!
I installed MariaDB on my Arch Linux system yesterday. Works a treat. Easy to setup and configure. Lightweight and fast. Can't believe its free :).
I say go for it.

I am developing client server application using ASP.NET together with MySQL. This solution will be hosted using VPS and of course I will install MySQL in VPS.
This web based application is a customized solution based on my customer requirements and I have no idea whether I can use MySQL community edition or I have to pay?
Thanks in advanced.
The question (and the answer) does not apply to MySQL only, but to all GPL-licenced software.
There is nothing to pay to use a piece of GPL software. MySQL Community edition is licensed under the GPL-v2 licence.

I need reproduce the exact same environment of a system in production, it's working with mysql 4.1.3b-beta-nt-max version, where I can get this exact version? I have looking with google but it seems like it's no longer available anywhere.
Thanks.
Try searching historical databases such as
http://www.oldapps.com/mysql_server.php?old_mysql_server=131
...in a pinch, you can install a "similar" version (such as the one above, 4.1.3beta-win), and then replace the binaries with the production ones. MySQL doesn't do strange things with the registry, so this procedure should suffice.

I want to create a website in JSP and the database will be MySQL. I will host the website on the internet. Is it required to obtain any licence to develop them on my machine?
As http://mysql.com/products/ states, MySQL database has 4 editions.
For development it is enough to use community edition, which is distributed under GPL license, which is open-source license.
You don't need anything.
No it'f free if you don't intend to sell the product including the mysql database software. Found here.

As funny as it is, most good MySQL editors are Windows based.
I am looking for a tool (US$400 top) for Ubuntu that can:
Auto complete tables and fields names + reserved keywords.
syntax coloring.
inline row content edit.
copy tables/databases from one host to an other.
I think the best Windows based is SQLyog, but it is a nightmare working on Wine.
I highly recommend DbVisualizer. It's a Java application and runs on Linux, Mac OS X and Windows. The MySQL JDBC driver is bundled in the package.
you might look at these sql clients below, all of them are open-source:
