Where is the fuzz on that first one, just the leaf edges or all over the leaves? Can't tell. Kind of thinking Echeveria setosa var ciliata or a young Aeonium tabuliforme, which has those whiskery edges when small. Not an Agave. #4 yeah Haworthia attenuata.

You need a grittier mix for those plants most especially the cactus, to avoid rot.

I'll second what hoovb said. That soil looks too wet. Repot in 50/50 cactus/succulent mix and perlite. Good looking plants.

I can't really tell either, there may be fuzz starting to form on the leaves, still too small to tell.

also, it IS potted in cactus soil.. that just happened to be right after a watering. I don't water anymore though, I use a spray bottle.. They're too small to be drowning.

Sadly, just because a bagged soil is called 'cactus soil' that doesn't necessarily mean it's any good for cacti and succulents as we've said many times before, it's just sales blurb. They will die in that mix whatever their size, large or small, the result will be the same. Can't tell what the planter/s look like size wise in relation to the plants or whether it's one big planter, but whichever, there's way too much unused 'peaty' type compost. It will cause one of two things to happen...if you water thoroughly which they will need (but they also need to drain properly) it will stay wet and they'll rot. Failing that, the soil may become hydrophobic, you will think you are watering it but it will stay dry at the roots, as spray bottles don't water efficiently. Please do a search for a more suitable mix using the search box a the top, your plants will thank you in the end.

Will do, still want to know what types of plants these are though.. Any further help is appreciated.
