Help with caring for potted plants?

Okay, so thing is, my dad's OBSESSED with plants and recently he had to go back to korea, his home country, for some work- where he's going to be gone for a LONG time. And so, he left me in care of his 11 little babies until he gets back. Lol. He left me with a lot of instructions on how to water them, but I'm still confused and I have no clue how to care for plants. I always kill my flowers ;^;

I honestly love plants as much as he does, but I don't know a single thing about caring for them. I tried to research the concept, but I still don't understand much...

I'll try to name the plants based on my research, I'm guessing though. So I have:

- 2 bamboo plants (which I think I can care for. Watering them is pretty easy because its not often, but info on them would be nice!)

- 4 Pothos (These I find the hardest to water...)

- 1 Croton

- 1 Dracaena (I'm not sure if this is the plant, but it looks similar.)

- 1 Snake Plant (This one I'm really not sure about, but my plant looks nearly the same, except not as yellow.

- 1 Aloe Vera

- 1 Small, common flower plant (Not sure what species...)

So, those are the plants I have, or at least ones close to them. I'm not sure how to water them really... I heard you're supposed to at least water them around 3/4, maybe more, into the pot, and do it again. I'm not sure though and I'm afraid I'll over-water them and kill them all. I really need help with this, I really don't want to kill my dad's precious plants ;~;

Oh, yeah. And other tips would be great to! Like, what do plants enjoy? I heard they love to listen to music, lol, so I usually leave the radio on for them owo. But, I mainly need help on watering- excruciating help, any help is welcome though! Thanks for the help!
