By calculating one of my RLC filter circuit values, I got L=3.8*exp(-10), C=6.6*exp(-11) and R=8.3*exp(5). My question is: 1. Are these values of R, L and C practically realizable? 2. Is it normal that we get these types of values, let suppose for L=3.8*exp(-10)?

R and C are realizable , L is not. It looks like you plugged some values into a cookbook formula and are trying for a 1 GHz corner or center frequency. Can you provide more details?.
