What is the duration of temporary ban on editing or suggesting edits?
Currently, it's 7. From this main meta post,
No, but repeated edit suggestion rejections from multiple users will cause your edit suggestion rights to be suspended for (n) days, where n is currently 7.
Looks like you have suggested 12 edits and half of them were rejected. That's 50-50. Since you're banned on March 28th, and it's April 4th, so the ban should be over anytime soon (I see @Iandotkelly has removed it now).

IMO, even all approved2 edits among approved ones are also not worth approval.
How can this ban be lifted from my account? How can I recover my editing rights?
I am not sure if moderators can lift the ban. There is no meta post I could find regarding this. So, I'd suggest that you should at least wait for the ban to lift and then make good edit suggestions that improve posts (but avoid trivial edits).
Try to follow the rules for suggested edits. You can start from here. And for the current tag wiki edits, see this post
