Running multiple Thread Groups sequentially in JMeter

Question

I have a Test plan in which there are multiple Thread Groups.
I want to run all of the Thread Groups sequentially.
Thread Groups are as below:

Thread Group1
Thread Group2
Thread Group3
. . .
Thread GroupN

I've read in different blogs and articles on the internet, people claiming that the thread groups will run in the order they are defined but apparently they are not in my case. Thread Group4 runs before Thread Group1. Thread Group4 is generating a report which is wrong because it runs before Thread Group1.

How do I ensure the ordering of my Thread Groups?

Also, I need to implement the following scenarios:

Run a single request multiple time by a single user (Single user should create 1000 accounts from a single HTTP request).
Run a multiple requests multiple times by multiple users simultaneously (Multiple users should create 1000 accounts simultaneously from a single HTTP request).

How to do so?

PS: Please read and understand the query carefully before replying.

Please create better separate ticket for the second part of your question (about another scenarios implementation): you are asking about quite a different things in the same question - looks to be not very appropriate. — Aliaksandr Belik

Concerning consecutive execution of thread groups in test plan: simple check Run Test Group consecutively check-box on the Test Plan configuration screen:

enter image description here

Use e.g. Loop Controller for this:

Thread Group
Number of Threads = 1
Loop Count = 1
  ...
  Loop Controller
  Loop Count = N
      HTTP Request
  ...

or even schema without Loop Controller but not so flexible:

Thread Group
Number of Threads = 1
Loop Count = N
  ...
  HTTP Request
  ...

Use Number of Threads property of standard Thread Group for this together with Ramp-Up Period property:
```
Thread Group
Number of Threads = N
Ramp-Up Period = 0
Loop Count = 1
  ...
  HTTP Request
  ...
```
This will start N simultaneous threads executing same scenario.
