If yes, which ones should we prioritize to learn first?

Active HelperWhatever makes sense considering your life in particular.
It depends on the area you live in and your job.
Do what is useful for yourself. Are you in a location where people are often speaking another language? Then it would be helpful for you to understand some of that.

I would prioritize studying languages that will be useful to you and that will lead you somewhere. I wouldn't waste time studying languages that you will most likely never use like many people do these days, but the choice is yours.
