Okay, your question was:
"what were the first five Transformers toys to have ball-and-socket joints?"

By that wording you must accept any of the first five Transformers toys that were created with ball-and-socket joints. The only way those answers can be wrong is if there are five other TFs with ball-and-socket joints which pre-date them, and this includes Wreck-Gar (1986).

...Huffer and Quickswitch??
