Converting names into coordinates is called geocoding. The most popular geocoder for OSM is Nominatim but there are other geocoders, too.

In case you choose Nominatim then please read the usage policy of OSM's Nominatim instance first. If you can't comply with them then you can either use MapQuest's Nominatim instance which has a little less restrictive usage terms, or just install your own Nominatim instance for unlimited access.

Other public geocoding services will have similar terms of use.

I read nominatim on wikipedia and what do you mean "Maximum of 1 request/s" one request for second?

This is not wikipedia, it's OSM's own wiki.

An "absolute maximum of 1 request/s" means that you are not allowed to send more than one request per second to OSM's public Nominatim instance. If you need more requests then check out the alternatives I mentioned before.

scai I decide to use ArcGIS REST API to convert address in coordinate. I read the documentation and I see that I must pay if I use particular operation. I need to use a web service that I can call very much and the web service must be free. Do you know if this web service has a limitation in number of calls that I can do in a day/hours/ etc?

I don't know the ArcGIS REST API and this is not the right place to ask questions about it.

You don't need to pay for using Nominatim. Just either comply with the usage policy of the public instances or install your own server.
