The suits in the background of Iron Man 2 are from left to right
Mark 1 (escape from the cave), Mark 2 (silver which Rhodes takes and creates war machine out of), Mark 3 (which he fought Obidiah in) Mark 4 (which he wears at the start of the movie) There is also the mark 5 - the portable suitcase suit and the mark 6 with the triangular chest piece. The mark 6 is a modification of the mark 4, which was a bit chunkier than the mark 3.

Like the NOES idea, might be a bit hard to make though. Imagine waving 4 1" blades about, it would be a bit heavy
