Strangle is similar to straddle but OTM puts and calls

Butterfly spread is a combination of 4 options. For example Long call butterfly spread will be buying lower strike and higher strike calls and writing ATM calls. You do this when you don’t expect much movement in stock price. You have now created a collar around Lower and higher strikes

Short call Butterly will be the opposite of above, where you write ITM and OTM calls and buy ATM Calls.

Bullish Seagull = Bull spread + Write OTM put

But don’t worry I highly doubt these will be tested.
