Can I post logo’s of technologies (C#, SQL, MySQL, ReactJS, JQuery) on my website?

Can I post logo's of technologies (C#, SQL, MySQL, ReactJS, JQuery) on my website?

Or, would that violate some copywrite agreements..(with Microsoft, Oracle, and the like)

I did some reading on this and it seems like you can as long as you don't claim to own it, but I didn't see it spelled out in black and white anywhere..

Basically i'm just building a contracting website and id like to show logos of the techstacks available, but I don't want to get into trouble for using those pictures.

What do you think?
