“Yeah” has 2 distinct senses listed in this dictionary. The most common is: an informal way of saying "yes.".

Both are affirmatives, but 'yes' is the standard, neutral form suitable for any setting, while 'yeah' is relaxed and casual, used mainly in speech among friends. In an interview or formal document you would write 'yes'; chatting with a friend, 'yeah' feels more natural and friendly.

Generally no. 'Yeah' is informal and belongs to casual conversation, texting, and dialogue, not to essays, reports, or business correspondence. In those settings, use 'yes.' Writers do use 'yeah' deliberately when quoting speech or creating a relaxed, conversational tone, but it is out of place in formal prose.

Not in itself. Among friends and in relaxed settings, 'yeah' is perfectly friendly and normal. It can seem too casual or slightly dismissive in formal situations, such as answering a manager or teacher, where 'yes' shows more respect. Tone and context decide how it comes across, not the word alone.
