Thank you in advance

#3 -- ... to participate in the conspiracy ...

#9 -- ... during Shakespeare's time ...
"own" not "owns"

#11 -- comma after "forty-five years"

Delete all in parentheses. The rest of the sentences are fine. For synonyms, remember to go to http://www.thesaurus.com

#11 is fine as is -- with a period at the end.

#12 needs to be two separate sentences and needs some commas after introductory clauses/phrases.
