Questions of indie and Mobile lisence

Nope, no limitation for sales in any of the licenses. Only how you distribute it.

indie single / multi: digital only (online stores, forums, etc for windows, mac & linux)

mobile: same as indie but can sell mobile app versions for iOS & android platforms too.

professional: same as above but can also sell physical copies in retail stores (probably requires a publisher like Daedalic or Deep Silver to do that though).

* note: mobile & professional licenses only cover 1 title (a single game). However the indie multi license is included in those licenses so you can keep on working on as many digital only projects as you like afterwards.

After make my games In first step I only want put them on Steam Win/Mac/Linux.
Mobile version relative to feedback of my games because this license is risky and pretty expensive and per title too.
