Multiple rows into one row

you can use transformer stage first to convert null to zero in case of integer , and to empty in case of characters , then use aggregator stage to get max value for integer , and sum for characters , or you can use sum for both , try this , i think it will work

Signed numeric

if the data contains no decimal , use integer , if it contains decimal values , use decimal or double , but i prefere double because it doesn't preserve space for the datatype like decimal , it preserve space for the value it contains , so use double without specifying size or precision
