This is in reply to your 8/03 post RE: Donna Danna: 08.03.26: window of plagues

I don't know how long it took for the 10 plagues to take place in Egypt, and people have different opinions about it. Even the Jewish people can't agree according to the article at Ask the Rabbi, JewishAnswers.org » How Long Were the Ten Plagues? which states the following:

How Long Were the Ten Plagues?

Question: How long did the ten plagues last?

Answer: According to the Mishnah (Eduyos 2:10), the punishment of the Egyptians lasted for 12 months. This implies about a month for each plague; some say that each plague lasted for a week and was preceded by a three-week warning, and some say the reverse. According to both of these views, the time between the first and tenth plagues (inclusive) was at least ten months. But others say that the plagues lasted for only about 10 weeks. In fact, the Torah says that the first plague lasted seven days (Ex.7:25), and some of the plagues lasted less than seven days; the darkness lasted three days (Ex.10:23), and the firstborn died at midnight of one night.

Yours, Rabbi Azriel Schreiber 

It is either going to take 3 1/2 years or 7 years for the 4 seals to be opened, the 7 trumpets to be blown and the 7 plagues to be poured out from the 7 bowls or 7 vials. I don't know how long each one will take separately because the Bible doesn't say.

You also asked the following questions:

Will some of the plagues come in rapid succession?

Or will there be any window of time between some of the plagues to allow a space to repent?

Many, apparently won't repent, but some might, and may end up believing in Jesus, possibly be martyred, and not take the mark if the beast?

The 7 plagues are poured out on those who have taken the mark of the beast. Once a person has taken the mark of the beast they don't repent. Rev. 16:2 says,"And the first (angel) went, and poured out his vial upon the earth; and there fell a noisome and grievous sore upon the men which had the mark of the beast, and upon them which worshipped his image." Rev. 16:8-11, "And the fourth angel poured out his vial upon the sun; and power was given unto him to scorch men with fire.  And men were scorched with great heat, and blasphemed the name of God, which hath power overthese plagues: and they repented not to give him glory. And the fifth angel poured out his vial upon the seat of the beast; and his kingdom was full of darkness; and they gnawed their tongues for pain, And blasphemed the God of heaven because of their pains and their sores, and repented not of their deeds."
