can anyone suggest me that, can i use a Attiny85 instead of Arduino uno board? and how it can be posible?

Yes.

If you are only using a few IO pins and have no special requirements for speed or other facilities found in the ATMega328 and not in, for example, an ATtiny85.

The ATtiny45 or 85 is a great option for running simple Arduino programs: it’s small, cheap and relatively easy to use. It does, however, have some limitations relative to the ATmega328P on an Arduino Uno. There are fewer pins, meaning you can’t connect as many components. There’s less flash memory (4KB or 8KB instead of 32KB), meaning your programs can’t be as big. There’s less RAM (256 or 512 bytes instead of 2KB), meaning you can’t store as much data. And there’s no hardware serial port or I2C port (Wire library), making communication trickier. (There are workarounds, like the SoftwareSerial library or the TinyWire library, but they’re not as robust and flexible.)

In short, then, if your project requires only a few simple inputs and/or outputs, you’re probably fine using an ATtiny. If you’re trying to hook up more components or do more complex communication or data processing, though, you’re probably better off with something like the ATmega328P on an Arduino Uno. If you want something smaller and cheaper than a full Arduino board, you might try using an ATmega328P on a breadboard instead.
