Thanks for the comments once again. Maybe if I were a little older, weed would be possible, but not now. And Corleone: that depends how much chili I get 
Some pictures from today:
Tomatoes

They seem to be doing well. I spray them with water every now and then to simulate a higher air humidity.
Clementine

There's five of them now (I sewed 10), the one on the right that's taller and doesn't look like a clementine has popped up pretty random there, but I think it's a tomato or paprika seed ending up a little wrong. There's another similar one that's popped up on another place I haven't sewed anything, that looks like this as well.

This is how they look after the re-planting. Poor light in the picture, but most of them (all except two to be exact) are standing up on their own now.
Paprika

And this is how they look after the re-planting. They are not having trouble standing up by themselves, perhaps a little because I planted them far down. That's also the reason they look shorter now than in the first picture.

Doing fine as well. Might actually be time soon to plant them in pots, but I'm going to wait a few days before doing that.
It seems that the avocado is not going to grow, but I haven't given up hope on the oranges yet though. Considering the clementines took a long time before growing, there's still a chance the oranges will show up one day.
