Which addons do I have to use if I want to start from about 1850 and to have some vehicles but the graphic to be good even with extra zoom , and the buildings also to look older , the have many industries , the towns to have a different growing system and new vehicules and buldings to be available beyond 2050.
The answer, in short, is that you will most likely not have all of these things together, especially easily.
OpenTTD will let you start a game in 1850. There are no sets which provide any buildings specifically for this era. The FIRS industry set does provide a few industries with buildings designed in this era, but most of them are not, and you can't select which industries to turn off and on unless you want to enable manual industry placement only. If you do that with the goal of only including era-appropriate industry buildings, you're going to be extremely limited. There are a few 8-bpp sets which do include some early trains, but eGRVTS is the only one that provides horses for transportation, as the motor vehicle didn't come into existence until the 1890s. Once you get into the 1900s you start finding more NewGRFs that slowly begin expanding the options of vehicles.
There are also not a lot of sets geared towards the future. A few buildings in the ECS Vectors industry set become ultra-modern, but that's really it. There are only a few sets which provide futuristic road vehicles, and a few more futuristic planes such as in in AV8, and a very few number of futuristic monorail and maglev trains.
There's yet another complication to throw in... even if you accept playing with these limited NewGRFs, it will take quite a few of them to achieve your goal of playing a game from 1850 to beyond 2050. There is a hard-coded limit of 64 (I believe) NewGRFs in the default OpenTTD build. You may not be able to include all the NewGRFs that you want. Your only way around this would be to learn how to compile/build your own version of OpenTTD which removes this limit, or use an altered "patch pack" set which has already removed them. In either case, you'll only be able to play such games on your own and not in multiplayer, and you'll only be able to share any save games with others who are running the exact copy of OpenTTD that you are. With a patch pack, you'll also have to accept playing with whatever additional features the set's author has included.
When you say, "but the graphic to be good even with extra zoom", if you're expecting 32-bpp sprites, you're going to be disappointed here as well. There is only one 32-bpp base set, zBase, which is still not yet complete, and only provides for buildings that maybe can be used as early as the 1920s for a compatible style. There are a couple of building and vehicle sets in 32-bpp, but none of them in the 1850s era again. 32-bpp graphics are only a recent addition to OpenTTD, and due to the complexity, computer resources and time it takes to create them, there are only a few artists who have been available to create them.
I won't say it's impossible to achieve what you're looking for, but it will likely be very difficult, and you may not be entirely happy with what you have to settle for in order to get there. You'll likely have to be very considerate as to what NewGRFs you do add, since once you start a game with a NewGRF, you cannot add or remove any more (at least, not easily and not without expecting complications which include corrupting your game and making it permanently unplayable).
