As some of the journals take months sometimes more than year to review the manuscript, is it technically, ethically justified to submit the same manuscript in two or more journal simultaneously to expedite the publication?
My advice is to choose a magazine (journal) that has published a previous work related to your field of (papers) researches. Submit your search to a specialized magazine and prepare the publication to find out how fast the reply. You can know the reviewers in the magazine before you send your job (work), choose the magazine that has reviewers related to your field and thus ensure the speed of reply. Before submitting your search (paper) there are many web sites that reduce the quote, improve the language and also provide a presenter that shows your work in a manner that attracts the attention of reviewers.

Of course "No". It is unethical. Some journals ask the author for stating that the submitted manuscript has not been published elsewhere or submitted for publication simultaneously.
It is not ethical. There may be a clash of interest or copyright infringement in the long run when the manuscript is eventually published by more than one journal. This could lead to the article being taken down by both journals.
