this address generated by EXchanger automatically that used for deposit . can i send coin to this address of electrum standard wallet without problem ?
Yes, you can send to any address from Electrum using any wallet type. The only restriction you may find is that some exchanges will not yet let you withdraw to a bech32 address. So if you made a Segwit wallet with Electrum that would be an issue but you can easily get around it by keeping 2 wallets. As you already said it is a standard legacy wallet this will not affect you.
