For example:
My humour isn't sarcastic enough.
I haven't seen its use in anywhere before. Is it okay to use? If not then what can be a proper way to say it?

Sarcastic is an adjective so yes, it's fine, but we generally don't discuss someone's "humour" unless it's a comedy act, e.g., "I really enjoy George Carlin's humour." For non-comedians, we'd say "your sense of humour is really sarcastic."
(I'm not sure when I'd ever tell someone they're not sufficiently sarcastic. Does the world need more sarcasm?)
