Please read the MQL4 documentation on — Access to Timeseries and Indicator Data

You can use the functions like the following to retrieve price quotes for different time-frames or symbols ...

iClose	Returns Close price value for the bar of specified symbol with timeframe and shift
iHigh	Returns High price value for the bar of specified symbol with timeframe and shift
iLow	Returns Low price value for the bar of indicated symbol with timeframe and shift
iOpen	Returns Open price value for the bar of specified symbol with timeframe and shift

   Same answer: perhaps you should read the manual. iRSI - Technical Indicators - MQL4 Reference

2. It is Mr B57: But i don' t know how to take value from M30 when EA is working in H1. 

   On MT4: Unless the current chart is that specific symbol(s)/TF(s) referenced, you must handle 4066/4073 errors before accessing candle/indicator values.

Something like this

double rsi60=iRSI(_Symbol,60,14,PRICE_CLOSE,1);
double rsi30=iRSI(_Symbol,30,14,PRICE_CLOSE,1);
Comment(rsi60," ",rsi30);

But, as others have said, you'll have to do something different to access the value for a different symbol than the chart your EA is on. (another topic);
