I haven't heard of this seven or several idea from anyone other than on this soap forum. At the moment, several to die is true.
The four deaths on-screen have been the helicopter pilot, Ruby, Ross and Val.
There may not be any more deaths but there are now consequential effects following the action at the village hall. It may take a long time for this storyline to come to its end though.
Debbie has smoke-inhalation injuries. Could these cause long-term health problems? (Charley Webb is due to leave soon for maternity leave anyway.)
Diane has head injuries. Could these turn out to be worse than presently thought?
Bob ends up in hospital this week after being badly beaten up in jail by a prison cell-mate who is a convicted murderer. How badly injured is he? Will he be imprisoned properly later if found guilty of bank fraud?
Alicia is going to leave for Portugal, possibly without David, and leave the soap this way.
Rachel is going to leave the soap soon. (Uncertain exit story for now.)
Could Chrissie and Robert find themselves jailed for their parts in the accident and the attempted cover-up by Robert?
My feeling is that Rodney, Joanie and Kyle have an unclear future in the soap at present.
There are also a number of other characters who are not very popular who could leave at some time (see this forum for suggestions for names of characters!). Matthew Wolfenden (David) said in a recent interview to the Daily Express that the present cast cuts are due to the need for financial savings to be made to the Emmerdale budget.
