Identification and Ficus Problems

Hello, I'm new here and you seem like a very friendly bunch. I would appreciate any help that you could give me with my plants.

I will have cats moving in with me soon, one who likes to nibble on plants, so I want to make sure any harmful ones are far out of reach or out of the apartment, but I don't know what I have! I have attached photos. From my research I suspect that Plant 4 is a Aluminium Plant but I haven't come up with anything on the others. Plant 5 has flowered? (Extra photo attached.)

On another note, it seems that I have over-watered my ficus benjamina. Leaves near the bottom of the plant are drooping and turning yellow and brown and falling off and there are brown spots on some leaves. The majority of the plant looks healthy and there is new growth. I moved him to a location with more sun. I was poking around in the soil in order to see how wet it was and found that there are a bunch of really tiny (less than 1mm long) white/silver bugs in the soil that I haven't been able to identify and this morning I found a centipede. I have now proceeded to panic. Should I re-pot it? (It's late fall/early winter here and the internet told me never to re-pot it in autumn.) Will the bugs go away when it dries or do I need to do something?

I will appreciate any advice that you can give. Thanks.

 

Welcome! maybe the third try will be successful!
1 - Looks like one of the jades. Probably Crassula ovata.
2 - Reminds me of one of the peperomias
3 - Hoya carnosa - wax plant.
4 - Yep! Aluminum plant
5 - No idea
When you do confirm all the id's I've found this link to be helpful.

1.0 Is Portulacaria afra .

 

Looks like:

1. Portulacaria afra, Elephant Bush;
2. Peperomia puteolata;
3. Ardisia crenata, Coral Berry;
4. Pilea cadierei, Aluminum Plant;
5. Dracaena surculosa, Gold Dust Dracaena.

 

Boy - I sure blew that one! Guess I really do need new glasses. ;-)) barb

 

Is that Gold Dust D. blooming...??? Cool!
(I was thrown by this one too, Barb---spots looked really white to me. Just did not register. AND I recently GOT new glasses, so...!)

In re the ficus situation: I think repotting should be postponed---it would be yet another stress on the plant, which has already been overwatered and I daresay is having a snit about its changed location. Unless the bugs start proliferating horribly, I say wait.
