The best way is to download either the Store only or combined install from here https://our.umbraco.org/projects/collaboration/merchello/, depending if you have Merchello already installed download the Store Only and just install the package in the packages section in umbraco. If you dont have Mercehllo installed, download the combined install and install that one in the packages section.
I would personally uninstall Merchello if it is already installed and then install the combined install. It will probably be a lot easier this way.
When I tried to use bazaar dll and create view I have such error
Cannot cast source content type Umbraco.Web.PublishedCache.XmlPublishedCache.XmlPublishedContent to view model type Merchello.Bazaar.Models.ViewModels.AccountHistoryModel.

orders for current member
How I can create page on front end with list of orders for current member?
See my answer to your other similar question here
The Bazaar starter kit has an Account History template which will be a good starting point.

but if I have a lot different setting, can I set up some controllers, because I need only history?
If you have already done a lot of work on it then yeah you might want to create something that does what you need, in that case look around here https://github.com/Merchello/Merchello/tree/merchello-dev/src/Merchello.Bazaar to see how bazaar actually does what Barry mentioned earlier.
