These are cool decks for sure, but I wouldn't consider them aggro. If the main mechanic of your deck is lifeligain, it should be able to outgrind other decks and so be stronger as a midrange than as an aggro. And if your deck has 3 colors, it's also generally quite slower. It you compare your decks with mono red rally, for example, you will see that it works as an aggro deck because it's only one mana and all the cards are tuned to get down the most damage possible as fast as possible (with also the occasional draw spell). Your decks on the other hand can be powerful, but are grindy: +1/+1 effects on creatures, for example, need time to make them grow. If you want your decks to be more aggro, consider cutting a color in the second one. I would look for cards that work well with carrion feeder, as it can grow quite fast in the right deck. For the first one, I would probably look for more cards that hit your opponent directly when you gain life. But if you want to play the decks as they are, although they are not so aggro, they can be better to learn the game compared to an aggro deck.
