Planning to create 10 wordpress sites. Started the first one. I got few questions.

Hello,
I have bought some old expired domains. They all have keywords that i liked, good Trusted backlinks and not spammed. I have nearly 10 of them now and started to creating web sites. I have some questions on my mind.
All will be on different keywords. I am not planing a private network. They will not be linked to each other.
1- I will use same default addons for all my websites and same wordpress settings. May be even same theme. Is there is an wordpress plugin or software that i can copy my first web site then clone other 9 sites. Like just default startup settings.Only Then i will start adding separate content to all each other sites.
2-I will Host all sites under one Hosting plan. Is this will cause any Ranking negative effect?
As i told all sites are on different niches. One about fitness other about music-arts another about computer software's.....
T1 links also will be from different web2.0 accounts.
3- If i will use one adsense account for all the sites is this may cause problems?
4- I should ever never add link to each other? As they are nearly clones to each other. {Content will be different at all}
Thanks.

1. I don`t recommend you to use the same theme... Google will consider them as duplicate
2. If you will host them under one hosting plan Google will know and it will make the connection between them.
4. If you make link exchange between them Google will not take into account your links.

I would recommend buying in to a PBN network, there should be sellers here. Don't waste your time, when you can purchase something already made and done the right way
