Sup, yall, this is DJ(not quite yet, but..)Raja, Before I ask any questions, I'd like to say thanks for the previoius answers you guys provided on the forum, it helped me alot. And,as usual, I have couple of newbie questions, first of all, thanks to my small desk, I only have one turntable hooked to my mixer, I thought one turntable would do for just praticing techinques(of cource I didn't make much progress), so does two turn tables has to be hooked to the mixer in order to practice any techinques? And I saw some pro DJs with not so complicated looking mixers, I'm sure they got good skills, but can you do high level techniques with any mixer?, and last of all, what are some popular speakers or amps does DJs usually use? I'm looking to get a speaker, so any recomendation will be welcomed.

First of all Welcome to the forum!!!

You do not need 2 turntables to practice most of the basics you can practice with one even some of the advanced stuff. You should be fine with your mixer also. Remember the dj makes the equipment not the equipment makes the dj. For speakers I think maybe you should go with another turntable before you get a speaker but thats me. My recommendation and what I use is the American Audio APX series speakers either active or passive, they are great speakers and highly affordable!! Heres my APX review. Are you planning to do gigs? If not you can just get some small monitor speakers to practice with.

Two turntables are useful as you can put up a better show putting forward a lot more scratches a lot more quicker than you would with one. Generally scratch DJz use Scratch mixers which aren't quite complicated example QD5. I own one and its amazing.
