If i use a model as Allmaras or k-e(enhanced wall)and i want to take values of viscous sublayer, the Y+ plus it must be exactly Y+=1 or can be above and below from 1. With other words if i have Y+=0.1, the turbulent model will give me right results?

You can actually read up the User Guide, it will detail all the information regarding Y+ and the values required for each turbulence model. Look up section 12.11 of the FLUENT 6.3 User's Guide. You'll get all the information you need.

Hope that helps.

Ok... i have already reed these section of guide, but there dosnt write for Y+<1. At a point, report that you can use until Y+<4 to 5 for enhanced wall treatment but dosnt report for Y+<1.
