All objects that you will deal with consist of approximately equal numbers of positively and negatively charged particles (protons and electrons).

A static charge is created when something changes the ratio of positive and negative charges in an object. For example, if you rub two insulating objects together, you may transfer electrons from object to the other. One object will gain a negative static charge, the other will gain a positive static charge.

You can also place static charges on conductors which are insulated to prevent current flow. This is still a condition where you have a change in ratio between number of charges particles.

You can 'spray' objects with electrons. You can also induce charge on a conductor by putting it near another charged object. Lots of different ways to move charges around and create a difference in the number of protons and electrons in an object.

Just about anything that creates any form of electricity can create a static charge. It's what stores the charge that really makes any kind of charge static or not.

insulators can be a medium for static charge to build on, pos or neg charge.
a cap also (which is a fancy metal "insulator").

but something has to create it, usually "work" does. that work can be done to many different mechanical methods that can cause electric charge imbalance.
