It is almost impossible to run many EAs in one copy of MetaTrader.
It may be some case when many EAs wanted to open/modify/close the orders in the same time. It is just one case. But there are a lot of different cases why it is totally difficult or almost impossible to run many EAs in one Metatrader.

There are some (free) library files to do it. But and in this case it is difficult. Just select one or two EAs.

The other related thing is the broker. Every broker is having different data and some EAs (or most of them) are having different performance with different broker.

Just one example.
NewsTrader.5 EA is placing 3 stop orders in every side. 36 totally. SBS EA is placing 4 perding orders. TPE EA is placing the other 4. GridMACD EA and MaChannel is openning many orders during the day. Envelope 2.11 is placing many pending orders during the day at once.

So to use it in one copy of Metatrader it is necessary to have some special tool namely Portfolio Manager. We don't have it yet. I mean no where: no any commercial and no any for free. Does not exist yet. We wanted to start to create this kind of tool in elite section but seems it is very difficult.

My suggestion is the following:
start with broker (not all mentioned EAs are profitable with every broker), then - your deposit size (GoldWarrior02b, for examlpe, for big deposit size), then - your risk (GridMACD EA, TPE EA and MaChannel are risky EAs - just for example), then select one or two EAs only. Then try to look at the riginal threads to understand the trading system.
Do not trade EA with real money of you don't understand the system and why EA is openning the orders.
Then ask the questions in the forum. Which questions? For example: "what bad in this EAs? What is negative points for this EAs? I know that it may be profitable but when and why will I get the losses?".
Some people looked at the profit during the testing. The other people looked at the losses just to understand how to avoid it.

P.S.
7 EAs from your list are from elite section.
Please don't post it in public. I understand that it is easy to download all EAs and all the statements from one my elite section post or excel file ... But please ...
