使用する and 用いる are both formal, but 使用する is the standard term in official rules, manuals, and instructions, while 用いる leans toward describing methods or means.
利用する stresses making use of something to one's advantage (a resource, service, or opportunity), whereas 用いる is a neutral term for employing a tool or method.
活用する means to make full, effective use of something's potential, while 用いる simply means to use something without that emphasis.
用いる simply means 'to use' something for a purpose, whereas 生かす specifically implies exploiting something's value or potential to good effect.

率いる (ひきいる ) means to lead a group of people, while 用いる (もちいる ) means to use or employ a thing or method; the two are often mixed up due to their similar -いる ending.
