how much should i practice openings per week

ik i should focus on opening ideas, i already do that, i mean learn a new line

what do u use to learn an opening?

Depends on how well your doing with your current openings.

a good rule is the rule of thirds

1/3 Tactics

2/3 Playing & analyzing

3/3 Openings, Endgames, Positional play

4/3 anything else you can think of

i use books and chessable

I would review your Chessable every day if possible and do at least one variation each day

thanks

chessMakta is a YT channel that has some stuff

I also use Chessable, I'm also going to start studying/learning Chess tactics from the books as well.

im studying najdorf a few times a week

Sicilian's are fun

Close to 0, but if you can go lower than that, you should do so.

Lower than 0?

Yes, Sitbear means to try and actively forget openings
