what is the depth needed in the wall?

PDF spec sheet indicates 2 3/8 " needed assuming mounted to 1/2" drywall

Do you need a subwoofer for these speakers? Or do they sound ok without it?

I have a pair of these in a wall which are zone 2 speakers for a receiver which does music only and no subwoofer is possible (most receivers only have a sub input for zone 1). I have to say it sounds damn good, though I did place them up near the ceiling and close to walls to optimise the bass. So in this this situation you do not need a sub. If they are part of a home theatre setup then I'd recommend a sub (as I would with any speaker that is not floor standing capable to reaching some really low frequencies).

can I paint it with my wall color?

Yes you can paint it your wall color. The speakers come with a clear plastic insert which act as masks for the frame. The preferred and probably the best method to paint the frames and grill is with sprayed paint...you can spray your custom paint with a kit available at your better paint store. You can also use a small roller but be careful with the grill so that you don't fill in the hole. Several very light coats are best here.

I need them for a concrete wall. is their any problem ? what's the depth of the hole I need to make ?

I think you have many challenges with installing the Polk RC65i into a concrete wall. Overall dimensions (w x h x d) are 8 5/8" x 12 1/6" x 2 7/8". The RC65i requires a 1/2" or 5/8" drywall to mount effectively. If you have drywall over the top of your concrete wall, then this should work (although running the speaker wiring presents its own challenge). The opening in the concrete wall will be larger than the drywall (yet another challenge). I think I would look at a excellent Polk mini-speaker and surface mount that speaker versus tackling the "in ceiling speaker in a concrete wall challenge". But - if you make it work, post your solution to the community as I'm sure they would appreciate the how-to knowledge.
