If I wanted to make a programming language, what type should I make, so that it will be more likely to be used?
By type I mean: dynamic/static, lower/ higher level, OOP/Functional, C syntax/ Lisp syntax, ect.
With that said, if you want your language to be the next big thing you shouldn't just copy what all of the languages I mentioned above offer, invent something new! Come up with your own paradigm and syntax style that's better than what's offered now. I know it's easier said than done, but that's what it takes.
but how would I know what programmers everywhere want/need?
Look at the applications that programmers everywhere are working on. Look at what goes into making them, then look at the grievance that the programmers have with the tools that are used to make those applications. Now make a language that takes what they like from their tools, and fixes enough of those grievances in an eloquent enough a way that people will want to switch to your language.
Depends on the field. I currently work in IT as I finish my degree, and the programming we do is mostly scripting (little bit of python, shell scripts, and dabbled in expect for a little experiment). But I also work underneath the network admin here, so the programming is pretty minimal.
Place I may internship at next summer work primarily with Java. That place is an actual software development firm.
Everyone's problems are different. In my last place I faced constantly changing business rules, new and surprising hardware, hard realtime requirements for the critical paths through our software, ever-growing reporting and auditing requirements, full responsibility for any damage or loss caused by our products. This was solved with carefully-designed C++ core and a proprietary domain-specific language for business.
Development of a useful and successful computer language is almost always done as part of some other task.
For example, C was created to invent Unix at AT&T.
Pascal was created to teach programming at ETH Zürich.
C++ was created to help with distributed operating system management at AT&T.
PHP was created so Lerdorf could track visits to his online résumé.
Tcl was designed to help create integrated chip designs.
