Champions/ main lane

Hallo! i reached the 30 lvl before some weeks and I have not still experience so I would like to give me some tipps. I want to main two lanes and play 3-4 champions of each of them. The problem is that I want to be sure that I will select the two which I will like the most and be better in these than in the others. I know that in order to be sure I have to try all lanes with a lot of champs . This moment I can play top with malphite tryndamere and pantheon and I am learning Fiora In jungle I can play xin zao and master yi In mid fizz lux and I am learning lb In support blitz and soraka and in Adc only tristana and a little bit caytlin. As you See the number is very low. If you can I want to give me advice about how many champs I souls have in every lane ( and maybe some names) in order to make my decision.
