In short, no. Altcoins uses different languages that they code in. Bitcoin uses SHA-256, litecoin uses scrypt and so does dogecoin I believe. You need to purchase a miner coded specifically for what you are planning to mine.
which mean i can mine any altcoin with any scrypt miner ?
It all depends of what coin you want to mine. Each coin uses it's own specific algorithm, some have the same algorithm. You have to, in order to get profit, purchase a miner capable of the coin you want to mine's algorithm.
