Firstly, sorry for my english.

I'd like to know how can I know which font I can use for design my brand and my blog. I don't understand what does it means "Shareware", "free personal use"... and so on... I don't know which of these licenses I can use for my blog and my logo and brand.

Try Google Fonts for your webfonts.

https://fonts.google.com/

If your brand gets bigger, you can always change it to something more unique.

"Shareware", "free personal use" etc. means don't touch it with a 3.3 meter pole if you're putting it on the web or designing a logo with it unless it has a specific EULA or license agreement.

Shareware means that's just to test the font. If you like and you want use it, you have to buy.

"free for personal use" the most time means that you can use the font only for a non commercial use.
But you have to ask the author to know what it think exactly for the licence.

you could probably use a website somewhere that makes a font. idk
