As a general guideline, if you have several objects that you want to apply the same operations to, you should collect them into one data structure. Then you can use loops, [sl]apply, etc to do the operations in one go. In this case, instead of having separate data frames df1, df2, etc, you could put them into a list of data frames and then run na.omit on all of them:

dflist <- list(df1, df2, <...>)
dflist <- lapply(dflist, na.omit)
