a Affirmation Font

Hallo. My name is Nur. I'm going to start a small business and it requires a 'cute' font on my product (it's a resin craft). But I'm still don't understand about how these fonts are free for commercial use. May I know if this font is free for commercial use? And your other fonts too? Because I found them really cute and suits my taste. Thank you

it is free. any donation are very appreciated.
thank you
