 * Space Stone: Tesseract

Speculation:
 * Reality Stone: Aether. A lot of people thought it was Power until recent reports for Guardians of the Galaxy confirmed that the Orb was in fact the Power Stone, that makes Reality the next most logical choice as Malekith wanted to use the Stone to alter reality, reverting the Universe back to darkness.
 * Mind Stone: Chitauri Scepter. We don't even know if this one is an Infinity Stone but it controls minds, so... Mind Stone.

That leaves the Time Stone and the Soul Stone. Do you think we've already seen them in the MCU or are they going to show up in other films?

The Aether's abilities includes transforming all matter in the universe for making it totally black, thus, manipulatiing reality. Foster's and Malekith's absorbing it is a example for how it can become stored in something. Which is evenly displayed through the Power Stone. The Scepter's gem did everything the Mind Gem's for. That being the Mind Stone's definite. Those who inputted the Stones in these movies knowing which they are and not saying which the Aether is and that the Scepter gem's a Stone or not's likely for a puzzle we could play by thinking on these Stones until they tell us the truth of them. The Stones becoming absorbed into the Infinity Gauntlet shall look awesome.
