They look great. Whatever you are doing, keep doing it.

I guess I am more so worried about the second set.

They look good. The echeveria does look like it was etiolated, but now seems to be getting some better sun. It won't hurt the plant as long as it continues to get light. As it grows, you can behead it and get rid of the leggy part, or save it for propagation.

they look great! it's a lot easier to kill from over watering than under watering.

I am not sure about that echeveria, IMHO it doesn't look totally 'happy'. Your bowl-like containers - are they glazed? are there drainage holes?

To me it looks like the Echeveria is more unhealthy looking than healthy. It looks over-watered and stretched (etiolated) from lack of sufficient light. Community pots are okay as long as you are aware of the different requirements for each plant. As Rina mentioned it is important to have drainage holes. Glazed pots will take longer to dry out than un-glazed pots whether there is a drainage hole or not and do not get as much (or any) air to the root system. I grow in both terra cotta and glazed pots but am transferring more and more into terra cotta for their ability to absorb excess moisture and aerate the root system.

The new growth does look a bit better so you are likely giving it much more light than it was previously getting. The over-watered look may also be due to previous care and not necessarily anything you did once you acquired it. It may be beneficial to remove at least the Echeveria to inspect the roots for rot. If there are rotting roots they should be removed and allowed to heal before re-potting. Succulents can generally go a very long time between waterings, which is why they are considered to be drought-tolerant. If the roots are rotting and you continue to water the plant sporadically, the rot may spread to the rest of the plant.
