Yes, I have my own website.
I don't have my own, but I have contributed to a few.
I used WordPress as a back-office and Notepad++ for php, css, etc.
I have my own ecommerce website. I built it using a website building software and shopping cart software. Do your research to see what works for you. Try shopify, godaddy or wix.
it depends on the kind of website you want to create. For example, if you want to create a blog, the best platforms are Wordpress and Blogger (these are the ones I use). They are easy to manage and customize. You can add plug-ins and many features that will make it unique. I'd suggest those if you are about to get started.
If you already have some skills, as far as I know, if you want a domain (like... "nameofthewebiste.com" ) you have to pay for it. Here's a quick guide on How to Create a Website and more information about sites like Wordpress and Blogger. Hope this helps!
I've tried making my own website before didn't go so well. But I used Weebly.com. You can go to a You Tube tourtial for it and it will show you step by step on how to use it.
There are many, many ways to create a website, it depends on your time and willingness to learn. Depends also what you want to do with it, just as a hobby or commercial, or whatever.
One thing you could try is here: http://70b59e8rnff33o5dwht8zu3l5r.hop.clickbank.net/?tid=WEBSITEFORFREE
They give away free websites and also have premium ones for quite good prices.
Hope it helps.
