No not the rock band but this mishmash of spacefarers. I believe the centre 3 are inspired by a cultish westernised tv show but cannot see the origins of the big guy or the bot. Any suggestions?

Sold as a set by Khurasan. The vehicle in the back is a repaint of a toy I picked up ages ago. Part of a set that was contained in a fold out planet. I can’t recall the make or range. Googled it!
