Plugin Name check unique or not

I am new in WordPress but I wanted to know how to check my plugin name is unique or not and how to upload this plugin in wordpress.org. Please guide me how is it possible. ?
Simple enough, check whether the name you are going to use for plugin already exists in WordPress plugin repository. If not, then hurray... you can use the name and develop the plugin.
In case it exists, give your plugin a different name.
And to upload your WordPress plugin, please create an account and then follow the instructions

What if you update your version of woocommerce,What happned to our data?

What if you update your version of woocommerce,What happens to our data? Does it remain unchanged?
Your products, orders and customer data is stored in your database, so updating WooCommerce shouldn't affect them, but you should always backup your database before you update anything just in case something goes wrong. You can either use a plugin like WP migrate DB, or else export a copy of the DB via PHPMyAdmin.
If your theme uses custom templates for WooCommerce, these may have to be updated: WooCommerce will flag any templates that need updating.
If you've made any changes to the WooCommerce plugin files themselves you will definitely lose those changes: you should avoid editing plugin files directly.
Finally, it's worth reviewing the WooCommerce changelog to see what changes have been made and how they may impact you.

Can we lost any settings if we update plugin by single click?

I have a wordpress website. It will ask to update plugin again and again. So if i do these plugin update by clicking on update button, will any settings of plugin be lost ?
Whether plugin will get lost all previous setting or not, it is totally dependent on plugin logic.
E.g. I can develop a WordPress plugin which if somebody installs and updates later, can erase all previous setting. I can write a logic like that. So you can simply ask the same question to plugin developer as they can give you perfect answer.
