The sale END date has not yet been determined. So I cannot say for sure...but it should be there through the end of the month. Pending transactions fall off in 7-10 business days generally. Depending on your financial institution. You could try again now if you have the funds. It will not cause the others to "not" fall off. As they will automatically. but being multiple purchases from the same merchant may throw up a flag for your card company? It may be best to contact them to see why the error occurred in the first place and why the others were rejected to keep it from happening again.
