1) "What happen if we copy larger file automatically an the onedrive space is full and the onedrive recycle bin consume large capacity, will the copy file failed?"
If you do not have enough space in OneDrive, the copy will fail.
2) "Also can we disable or decrease onedrive recycle bin size?"
From my knowledge the recycle bin does not have a size nor can you decrease its size.
